Self assembly is an emerging technology in the field of manufacturing. Inspired by nature's ability to self assembly proteins from amino acids, this thesis attempts to demonstrate self assembly on the macro-scale. The primary focus of the thesis was to improve the design of magnetic tile self assembly. By constructing a flexible chain embedded with permanent magnets, self assembly is achieved through magnetic interaction. Theory has shown that such a chain is capable of self assembling into any 3D shape without self-intersection. The 3D shape created by the chain is predetermined by the sequence of the tiles. For this thesis, two chains were manufactured, each self assembling into one distinct shape. One chain self assembled into a sphere while the other self assembled into a '3-leaf clover'. An important characteristic shared by the two chains is that they both were constructed from 48 tiles that had the same proportion of north-pole and south-pole facing magnets. The difference between the two 3D shapes created is a direct result of the magnet tile sequencing, only. To connect the tiles, two different types of connectors were designed: one rigid and one flexible.
(cont.) The rigid connector design was able to stabilize the chain geometry; however some joints displayed excessive rotational friction. Additionally, the chain was not robust and was easily broken if dropped. When the chain was manufactured using flexible connectors, the amount of friction in the joints was significantly reduced. However, the chain lost geometric stability since the flexible connectors could not overcome some torsion forces created by the magnets. Ultimately, this thesis provided supporting data for the theoretical arguments concerning the ability of a flexible chain to self assemble into arbitrary 3D shapes. By predetermining a sequence of magnetic tiles, it can be known with certainty what shape the chain will assume. This thesis furthered the understanding of the mechanisms of self assembly, providing groundwork for the eventual application on the nano-scale.

ENGLISH ABSTRACT: This project investigated the feasibility of incorporating photovoltaic cells into plastic roof tiles using injection moulding. Such tiles have the potential to provide robust and distributed electricity contained within the building envelope. Current-voltage curves of amorphous silicon modules were measured under illumination using the PVPM 2540C power measuring instrument, both before and after moulding. The efficiency after moulding was reduced by 53% to 88%, with modules that were heated for longer being degraded more. Thus the duration of exposure to high temperatures affected the extent of performance reduction during moulding. This suggested that faster moulding at a lower temperature or faster cooling could solve the problem. Economic feasibility was examined by calculating the levellised cost of electricity provided by the tiles. A large-scale development in the Western Cape was simulated using a typical meteorological year of weather data and using the anisotropic diffuse irradiance model of Perez et al. (1988). Avoided costs due to replaced roofing, avoided costs due to electricity distribution infrastructure, and Clean Development Mechanism credits were accounted for. The cost of energy calculated was R11/kWh in 2010 rands, which did not compete with the price of conventional grid-based electricity at R1.8/kWh. The importance of the cost of balance-of-system components, such as the inverter, and not only of the photovoltaic modules, was highlighted for future cost reductions. Several clear guidelines for manufacturing photovoltaic roof tiles were discovered. The most important of these was that many bypass diodes make the system more robust.
AFRIKAANSE OPSOMMING: Hierdie projek het die haalbaarheid van die integrasie van fotovoltaïse selle in plastiek dakteëls deur spuitvorming ondersoek. Sulke dakteëls het die vermoë om robuuste en verspreide elektrisiteit te lewer, sonder om die gebou se vorm te verander. Stroom-spanning kurwes van struktuurlose silikon eenhede is onder verligting gemeet met die PVPM 2540C kragmeet instrument, voor en na spuitvorming. Die doeltreffendheid na spuitvorming is met 53% tot 88% verminder, met groter vermindering in die eenhede wat langer warm was. Dus het die duur van blootstelling aan hoë temperature die mate van vermindering van doeltreffendheid beïnvloed. Dit het suggereer dat óf vinniger spuitvorming by laer temperature óf vinniger verkoeling die probleem kan oplos. Ekonomiese haalbaarheid is ondersoek deur die koste van die elektrisiteit wat deur die dakteëls gelewer is te bereken. ’n Groot behuisingsontwikkeling in die Wes-Kaap is gesimuleer deur ’n tipiese weerkundige jaar van weerdata en die anisotroop model vir verspreide ligstraling van Perez et al. (1988) te gebruik. Vermyde kostes van vervangde dakteëls, vermyde kostes van elektrisiteit distribusie infrastruktuur en krediete van die Meganisme vir Skoonontwikkeling is in ag geneem. Die elektrisiteitskoste was R11/kWh in 2010 se randwaarde, wat nie mededingend met die R1.8/kWh koste van gewone netwerk elektrisiteit was nie. Die belang van die kostes van die res van die installasieonderdele, soos die wisselrigter, en nie net die fotovoltaïse eenhede nie, is beklemtoon vir kostevermindering in die toekoms. Verskeie duidelike riglyne vir die vervaardiging van fotovoltaïse dakteëls is voorgestel. Die belangrikste van hierdie was dat meer omloopdiodes die installasie meer robuust maak.

Umeå är en av de städer i Sverige som växer snabbast och innerstaden behöver förtätas för att lyckas tillgodose framtidens behov av bostäder. Att förtäta medför ett ansvar att ta hänsyn till stadens invånare och existerande byggnader. Det är framförallt unga vuxna som drabbas av bostadsbristen. Undersökningar har visat att många av de unga vuxna skulle vilja bo tillsammans med andra istället för att bo själva. Projektet förtätar varsamt en centralt placerad tomt i staden genom att dels bygga bostäder på underutnyttjad mark och dels genom att bygga på en redan existerande byggnad. Däremellan skapas samtidigt en innergård som delvis är publik. Projektet undersöker också ingående material och tektoniska aspekter genom att utveckla en keramisk fasad i hög detaljnivå. Undersökningen av det keramiska materialet bedrivs genom studieresor, tillverkning och modellering i fullskala. Projektet förser tomten I Umeå med ett genomtänkt förslag på förtätning av staden genom att kombinera undersökningar i både stor och liten skala.The fast growing city of Umeå needs to densify its inner city as a strategy to cope with its current and future housing situation. Densifying comes with a responsibility to care both for the existing inhabitants’ needs and the city’s built structures. It is largely young adults who are affected from the housing shortage. They often want to share their apartment with others, rather than living alone. The project deals with careful densification of a centrally located site by creating new structures on underused space, by adding to the already built and by creating a public space in-between. Furthermore, the project investigates the building’s material and tectonical aspects by developing a ceramic façade in detail. The investigation of the ceramic material is carried out through study trips, fabrication and modelling in full scale. The project provides the site in Umeå with an accurate solution for densified housing combining both large and small scale investigation.

This creative project is a brief study of clay tile surface decoration, using commercial 4" x 4" and 6" x 6" tiles, as well as handmade slab-rolled and slumped molded forms. The exploration of surface decoration was based on historical research. An attempt was made to bring these findings into a contemporary personal statement.In my research I found a rich and varied history of clay tiles and their functional as well as decorative uses. Historically, tiles have been used on floors, walls, pillars, ceilings, pathways, rooftops, doorways, and fireplaces in architectural structures. In this project I have explored the use of clay tiles as decorative and functional elements for a countertop and tabletop, and as decorative elements of freestanding objects (boxes). I have also experimented with a non-traditional approach of tile making, using traditional materials, by changing the tiles' two-dimensional surface to a three-dimensional form.Department of Art

Crowd simulations are being used in an increasing number of different applications, like evacuation scenarios, video games and movie special effects This creates a demand for crowd simulators that are simple to use and accessible to users of varying backgrounds. We will study the flow tile method proposed by Chenney [1], which provides an intuitive way of interactively designing divergence free velocity fields for various applications. A reimplementation of Chenney's method will be given and the implementation will be evaluated in terms of user-friendliness and how well the use of static spatially defined velocity fields suits crowd simulation. Furthermore the possibility of using the velocity fields for other related applications such as mobile robotics will be touched on as well.Simuleringar av folkmassor används i ett ökande antal olika tillämpningar, som evakueringsscenarion, datorspel och specialeffekter för film. Detta skapar en efterfrågan efter simulatorer som är enkla att använda och tillgängliga för användare från olika ämnesområden och bakgrunder. Vi kommer att studera flow tile-metoden som Chenney [1] föreslår. Metoden är ett intuitivt och interaktivt sätt att skapa divergensfria hastighetsfält för olika tillämpningar. En omimplementation av Chenneys metod kommer att ges och implementationen kommer att evalueras i termer av användarvänlighet och hur väl användningen av hastighetsfält som är statiska och definierade i rummet passar för simulering av folkmassor. Vidare kommer möjligheten att använda hastighetsfälten för andra liknande tillämpningar, som robotik, att diskuteras också.

Full textAbstract:
Wind-induced external and internal pressures on tiles installed on a low-rise building model with gable roof were investigated by using a full-scale wind testing facility generically named Wall of Wind (WoW). Emphasis was given to ridge tile where a failure usually initiates during extreme wind events. Three different profiles field tiles namely high, medium, and low were investigated in combination with two types of ridge tiles namely rounded and three-sided. Effect of weather block on the pressure was examined. The study produced a unique high resolution pressure data in the form of pressure coefficients (Cpmin, Cpmax and Cpmean) for field and ridge tiles. These tests revealed high pressure coefficients for the ridge tile compared to the field tiles including those at the corners. Ridge tiles at the middle of the roof saw slightly lower wind pressure compared to those close to the gable end. Weather blocking of clay tiles while useful preventing water intrusion, increased the wind loads on the field tiles. The case without weather blocking produced significant pressure underneath the field tiles that resulted in lower net pressures.

This thesis presents a case of study of the development and performance analysis of a surface grading application with real-time compliance.
We address the issue of spatial and temporal uniformity in the acquisition system. In a surface grading application it is crucial to ensure the uniform response of the system through time and space.
All the results presented for surface grading were obtained using real data from the ceramic tile industry. The VxC TSG database is public and can be accessed at www.disca.upv.es/vision/vxctsg.
We present a method based on soft colour-texture descriptors computed in perceptually uniform colour spaces. The method is parameterized and the involved factors are studied using two statistical procedures; experimental design and logistic regression. Although it is not a new theoretical contribution, we have found and demonstrate that a simple set of global colour and texture statistics, together with well-known classifiers, are powerful enough to meet stringent factory requirements for real-time and performance. Also the method is compared with two other approaches from the scientific literature; Colour Histograms and Centile-LBP.
Finally, we explore the method's capacity for on-line inspection in a study of real-time compliance and parallelization.López García, F. (2005). Real-time surface grading of ceramic tiles [Tesis doctoral no publicada]. Universitat Politècnica de València. https://doi.org/10.4995/Thesis/10251/1909

Thesis (MPhil (Public Management and Planning))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: The thesis examines whether a residential solar power system (comprising a solar photovoltaic [PV] system and a solar water heater [SWH]), a demand-side option, has a lower life-cycle cost than a coal-fired power plant, a supply-side option, or vice versa. It also investigates whether a million residential solar power systems could potentially replace a 4 800 MW coal-fired power plant in South Africa. The study also explores, should a million solar power systems be installed on residential units, what the total energy output, the equivalent in coal-fired generation capacity, and the comparative costs of the two power systems would be. The common belief is that solar PV technology is unviable for electricity production because it is too expensive compared to coal-based electricity. Statements such as these are made because the initial capital costs (procurement costs) are often used as the primary (and sometimes only) criterion for project, equipment or system selection based on a simple payback period. Due to life-cycle stages, often the real costs of the project or equipment are not reflected by the upfront capital costs. In this thesis, a methodology is developed to investigate the life-cycle cost effectiveness of a residential solar power system (comprising a 5 kW PV roof tile system and a 300 litre SWH) and a 4 800 MW coal-fired plant in order to choose the most cost effective alternative in terms of the project‟s functional unit (kWh). A 5 kW solar PV roof tile system and a 300 litre SWH system have been installed at Lynedoch Eco-village. The operational results from this experiment was used as a basis for developing a model for a million residential rooftops that will have a 5 kW PV roof tile system plus a 300 litre SWH system. The focus of the million rooftops model is operating costs over the lifetime of the solar power system, on the assumption that the capital costs will be financed from coal-fired generation capacity that will no longer be needed. The results of the study indicate that a residential solar power system is most cost effective over a 40-year life-cycle period in terms of the project‟s functional unit (kWh). The thesis also finds that a million residential solar power systems (comprising a 5 kW PV system and a 300 litre SWH) could potentially replace 40% of a 4 800 MW coal-fired generation capacity. In total, 2.3 million residential solar power systems are needed to replace a 4 800 MW coal-fired generation capacity. Emissions of 37 million tonnes of CO2 equivalent per year could be avoided if 2.3 million residential solar power systems were to be installed. However, the investment needed to install Lynedoch solar power systems (comprising a 5 kW PV roof tile system and a 300 litre SWH) on 2.3 million residential rooftops is fifteen times more than the investment needed to build a 4 800 MW coal-fired power plant. The investment needed to install 2.3 million Lomold residential solar power systems (comprising a 5 kW Lomold PV roof tile system and a 300 litre SWH) is six and half times more than the investment needed for a 4 800 MW coal-fired power plant. It was established during the study that if Lynedoch residential solar power systems were to be installed on the roofs of a million South African households, 152 308 jobs would be created in the manufacturing and installation supply chain. For the 2.3 million Lynedoch residential solar power systems needed to replace an entire 4 800 MW of coal-fired generation capacity, 340 690 jobs would be created in the manufacturing and installation supply chain. Installation of a million Lomold residential solar power systems would create 63 929 jobs in the supply chain. Installation of 2.3 million Lomold residential solar power systems would essentially create 147 298 jobs.
AFRIKAANSE OPSOMMING: Die tesis stel ondersoek in na die vraag of ʼn residensiële sonkragstelsel (bestaande uit ʼn fotovoltaïese (FV) stelsel en ʼn sonwaterverhitter [SWV]), ʼn vraagkant-opsie, ʼn laer lewensikluskoste as ʼn steenkoolkragsentrale, ʼn aanbodkant-opsie, het of omgekeerd. Daar word ook ondersoek of ʼn miljoen residensiële sonkragstelsels potensieel ʼn 4 800 MW-steenkoolkragsentrale in Suid-Afrika kan vervang. Verder word daar ondersoek, indien ʼn miljoen sonkragstelsels op residensiële eenhede aangebring word, wat die totale energie-uitset, die gelykstaande uitset van steenkool-opwekkingskapasiteit en die vergelykende koste van die twee kragstelsels sal wees. Die algemene oortuiging is dat sonkrag- FV tegnologie ongeskik is vir elektrisiteitsopwekking omdat dit te duur is in vergelyking met steenkoolgebaseerde elektrisiteit. Sodanige stellings word gemaak omdat die aanvanklike kapitaalkoste (aankoopkoste), gegrond op ʼn eenvoudige terugbetalingstydperk, dikwels as die primêre (en soms selfs die enigste) maatstaf tydens die keuse van ʼn projek, toerusting of stelsel dien. Die werklike kostes van ʼn projek of toerusting word egter dikwels nie in kapitaalkostes weerspieël nie, omdat hierdie maatstaf nie totale lewensikluskoste in ag neem nie. In hierdie tesis word ʼn metodologie ontwikkel om die lewensiklus-kostedoeltreffendheid van ʼn residensiële stelsel (bestaande uit ʼn 5 kW FV-dakteëlstelsel en ʼn 300 liter-SWV) en ʼn 4 800 MW-steenkoolkragsentrale te bereken sodat die kostedoeltreffendste opsie in terme van die projek se funksionele eenheid (kWh) gekies kan word. ʼn Residensiële sonkragstelsel bestaande uit ʼn 5 kW FV-dakteëlstelsel en ʼn 300 liter-SWV is in Lynedoch Eco-village geïnstalleer. Die operasionele resultate van die eksperiment is gebruik as grondslag vir die ontwikkeling van ʼn model vir die installering van ʼn 5 kW sonkrag-FV-dakteëlstelsel en ʼn 300 liter-SWV op ʼn miljoen residensiële dakke. Die fokus van die hierdie model is die operasionele koste oor die leeftyd van die sonkragstelsel, gegrond op die aanname dat die kapitaalkoste gefinansier sal word deur fondse wat nie meer vir die oprig van steenkoolkragsentrales benodig word nie. Die tesis se bevindinge dui daarop dat ʼn residensiële sonkragstelsel die kostedoeltreffendste is oor ʼn lewensiklustydperk van 40 jaar in terme van die projek se funksionele eenheid (kWh). Daar is ook gevind dat ʼn miljoen residensiële sonkragstelsels (bestaande uit ʼn 5 kW FV-dakteëlstelsel en ʼn 300 liter-SWV) potensieel 40% van ʼn 4 800 MW-steenkoolkragsentrale se kapasiteit kan vervang. Altesaam 2.3 miljoen residensiële sonkragstelsels is nodig om die kapasitiet van ʼn 4 800 MW-steenkoolkragsentrale ten volle te vervang. Gasvrystelling van 37 miljoen ton CO2-ekwivalent per jaar kan vermy word as 2.3 miljoen residensiële sonkragstelsels geïnstalleer word. Die belegging wat benodig word om Lynedoch-sonkragstelsels (bestaande uit ʼn 5 kW FV-dakteëlstelsel en ʼn 300 liter-SWV) op 2.3 miljoen residensiële dakke te installeer, is egter vyftien keer groter as die belegging wat benodig word om ʼn 4 800 MW-steenkoolkragsentrale te bou. Die belegging wat benodig word om Lomold- residensiële sonkragstelsels (bestaande uit ʼn 5 kW Lomold-FV-dakteëlstelsel en ʼn 300 liter-SWV) te installeer, is ses en ʼn half keer groter as die belegging wat nodig is om ʼn 4 800 MW-steenkoolkragsentrale op te rig. Die studie het bepaal dat as Lynedoch- residensiële sonkragstelsels op die dakke van ʼn miljoen Suid-Afrikaanse huishoudings geïnstalleer word, 152 308 werksgeleenthede in die vervaardigings- en installeringsaanbodketting geskep sal word. Met die 2.3 miljoen Lynedoch- residensiële sonkragstelsels wat benodig word om ʼn 4 800 MW-steenkoolkragsentrale te vervang, sal 340 690 werksgeleenthede in die vervaardigings- en installeringsaanbodketting geskep word. Die installering van ʼn miljoen Lomold- residensiële sonkragstelsels sal 63 929 werksgeleenthede in die voorsieningsketting skep, terwyl die installering van 2.3 miljoen Lomold- residensiële sonkragstelsels 147 298 werksgeleenthede sal skep.

Full textAbstract:
Nowadays, numerous applications of active sound transmission control require lightweight partitions with high transmission loss over a broad frequency range and simple control strategies. In this work an active-passive sound transmission control approach is investigated that potentially addresses these requirements. The approach involves the use of lightweight stiff panels, or tiles, attached to a radiating base structure through active-passive soft mounts and covering the structure surface. The resulting double-partition configuration was shown to have good high frequency passive isolation, but poor low frequency transmission loss due to the coupling of the tiles to the base vibration through the air gap. The low frequency transmission loss performance of the partition was increased by using the active mounts to cancel the local volume velocity of the tiles. The use of a decentralized control approach with independent single channel controllers for each tile facilitates the implementation of a multiple tile system in a large scale application.
A coupled structural-acoustic model based on an impedance mobility matrix approach was formulated to investigate the potential performance of active-passive tile approach in controlling sound transmission through plates. The model was initially applied to investigate the sound transmission characteristics of a double-panel partition consisting of a single tile-plate configuration and then extended to model a partition consisting of multiple-tiles mounted on a plate. The system was shown to have significant passive performance above the mass-spring-mass resonance of the double-panel system. Both feedback and feedforward control approaches were simulated and shown to significantly increase the transmission loss of the partition by applying control forces in parallel with the mounts to reduce the tile normal velocity. A correspondent reduction in sound radiated power was obtained over a broad frequency range limited by the tile stiffness.
The experimental implementation of the active-passive tile approach for the control of sound transmission through plates was also performed. Two main experimental setups were utilized in the investigations, the first consisting of a single tile mounted on a clamped plate and the other consisting of four active tiles mounted of a simply supported plate. Tile prototypes were implemented with lightweight stiff panels and integrated active-passive mounts were implemented with piezoelectric Thunder actuators. Both analog feedback and digital feedforward control schemes where designed and implemented with the objective of reducing the normal velocity of the tiles. Experimental results have demonstrated significant broad frequency range reductions in the sound transmission through the partition by active attenuation of the tile velocity. In addition, the experiments have shown that decentralized control can be successfully implemented for multiple tiles systems. The active-passive sound transmission control characteristics of the systems experimentally studied were observed to be in accordance with the analytical results.Ph. D.

Mestrado em Sistemas Energéticos SustentáveisA tendência de aumento do crescimento populacional e do consumo energético global obrigou a uma maior consciencialização da importância que os recursos energéticos representam para o desenvolvimento económico e social dos países. Assim, foi necessário desenvolver planos de intervenção para promover a sustentabilidade a nível global. A eficiência energética começou a aparecer como uma das possíveis soluções para todos os setores. A indústria cerâmica não é exceção à regra, no entanto, existe ainda uma grande margem de progressão. Este trabalho apresenta uma metodologia para a análise do potencial de diminuição de consumo de energia elétrica para uma empresa cerâmica, no entanto poderá ser aplicável a toda a indústria. Pretende-se assim avaliar a possibilidade da substituição de iluminação, motores e compressores por tecnologias mais evoluídas, que possibilitem a diminuição da faturação energética. São apresentados procedimentos para o levantamento de dados bem como, depois, para a análise das potencialidades de aumento de eficiência energética. Para isto foi utilizado um analisador de energia, uma câmara termográfica, um tacómetro, os software Dialux e MATLAB, que permitiram simular os casos de estudo presentes na empresa. Pode-se afirmar que caso todas as mudanças propostas sejam aplicadas será possível diminuir a intensidade energética e o consumo específico em 0,74 %, investindo-se 83061,25 € proporcionando uma poupança anual de 35112,11 €. Assim o retorno médio esperado será de 2,37 anos.
The trend of increasing population growth and global energy consumption led to a greater awareness of the importance that energy resources represent for economic and social development of countries. Therefore, it was necessary to develop intervention plans to promote global sustainability. Energy efficiency began to appear as one of the possible solutions for all sectors. The ceramic industry is no exception, howerever there is still a large margin for improvement. This project introduces a methodology for the analysis of power consumption reduction in a ceramic company, although it can be applied to all industry facilities. The aim is to evaluate the possibility of replacing lighting, motors and compressors for more advanced technologies that reduce energy billing. Protocols for collecting the necessary data, as well as for analysing the increase in energy efficiency are also defined within this work. Therefore an energy analyzer, a thermofgraphic camera, tachometer were used. Also the software Dialux and MATLAB were used to simulate the case studies in the firm. It can be stated that if all the proposed changed are applied, it will be possible to reduce energy intensity and specific energy consumption by 0,74 %, by investing 83061,25 € that will provide an anual saving of 35112,11 €. Thus the expected average return is 2,37 years.

The history of polychrome glazed objects in Iran is synchronised with the history of the first known
examples of polychrome glazed artifacts. The polychrome glazed bricks of Chughā Zanbīl, dated back to
the thirteenth century BC, might be the first evidences of such a claim. This tradition was followed until
the fall of the Achaemenids in the fourth century BC, when glazed bricks objects were vastly used to
cover the friezes of palaces and important edifices at Persepolis and Susa. Making polychrome glazes on
ceramic materials, however, seems to be abandoned until the Islamic period, when polychrome underglaze
objects were widely in use in Iran from the tenth century onwards. The first evidences of creating
overglaze polychrome decoration was nevertheless achieved on mīnā�ī glazed objects in the thirteenth
century AD, which as Abu’l Qasim stated used be originally called haft rang, e.g. ‘seven colours.’ This
technique was slightly modified and used throughout the fifteenth and sixteen centuries in Iran, and then
was extensively used in the seventeenth century over the Safavid period (1501-1736). In all these types of
polychromies, a dark colour line (mostly black) is used to separate various coloured glazes. This technique
is still alive and is widely used in decorating the architectural facades of scholastic buildings in Iran. In the
twentieth century, art historians attributed this type of polychrome technique to a Spanish style of making
polychrome glazed objects called cuerda seca. The only feature by which such an attribution is
established is a ‘black line,’ which is used in both techniques of haft rang and cuerda seca for separating
coloured glazes.
This thesis provides firsthand information about the seventeenth century haft rang tiles in Iran using
various analytical approaches, including optical microscopy, wavelength dispersive x-ray fluorescence
(WDXRF), x-ray diffraction (XRD), densitometry, ultraviolet visible spectroscopy (UV-Vis
spectroscopy), micro-Raman spectroscopy, and energy dispersive x-ray spectroscopy (EDS). Here, optical
microscopy was mainly used to have a general idea about the stratigraphy and various layers of the haft
rang tiles. WDXRF was however used to respond to the question of the provenance of the tiles as this
subject has always been of interest to frame the archaeological context of haft rang tiles. Another issue
emphasised in this thesis is the thermal history of the tiles, which was studied by XRD and measuring the
density of the bodies’ tiles. This subject was particularly was interesting for me to delve into because
multi layer structure of haft rang tiles makes the study of thermal behaviour of the bodies much
complicated. On the other hand, the study of the coloured glazes was firstly achieved by UV-Vis
spectroscopy, where the possible colourants and network modifiers of the glazes were studied. Micro-
Raman spectroscopy, however, presented very notable results about the opacifiers and un-dissolved
particles suspended in the glazes’ matrixes. EDS microanalyses were nonetheless carried out to have a
general idea about the chemical composition of the glazes and their fluxes, opacifiers, and network
formers.
ii
The results of the aforementioned studies showed that, regardless where they are found, the bodies of
the seventeenth century haft rang tiles are local products and are not imported from other centres of tilemaking.
Moreover, under the optical microscope three layers of a terracotta body, a white glaze, and
coloured glazes could be observed in a single haft rang tile from the bottom up to the top of the tile. In
addition, the thermal history of the tiles’ bodies showed that the tiles were not fired most probably at
temperatures higher than 1000°C. In fact, the equivalent firing temperature (EFT) of the majority of these
tiles was estimated to be between 800 and 1000°C. As far as the white glaze is concerned, it was achieved
by dispersing tin oxide particle in an alkali glaze as opacifier. The lead content of the white glazes can be
technically associated with the manufacturing white glazes in medieval Iran, where tin and lead was
roasted to make an opacifier for alkali glazes. Another issue concerning the white glaze was its maturing
temperature, which was estimated to be at about 850°C. The yellow glazes were however achieved by
dispersing lead tin yellow particles in a lead-based glaze. The green and brown glazes were practically the
yellow glazes in which copper(II) and iron(III) respectively used. The maturing temperature of the yellow,
green, and brown glazes was calculated to be roughly placed at 615°C. The blue, violet, and turquoise
glazes showed however different behaviour by an alkali matrix in which cobalt(II), manganese(III), and
copper(II) had yielded the blue, violet, and turquoise tones. The maturing temperature of these glazes was
assessed to be at about 700°C. The black lines did not show to be true glazes due to the high alumina and
manganese oxide contents in their composition. The high maturing temperature of about 1150°C of the
black glazes revealed very interesting results. This property has certainly been of interest in manufacturing
haft rang tiles; that is, when the low temperature glazes were runny enough to be mixed together, the
black line was resistant enough to keep separated the glazes in order not to run together. The relatively
higher maturing temperature of the white glaze has also been desirable since it does not softened in low
temperatures at which the upper coloured glazes were runny and the chance of mixing the white glaze and
the upper glazes was substantially lessened.
Another subject on which this thesis shed light is the attribution of haft rang technique to the Spanish
technique of cuerda seca. In the discussion and final chapters of the thesis, an attempt is made to put
together the technological features of these two techniques. What can be at least understood on the
evidences exist about these two techniques is that there is no technological reason by which haft rang
technique can be attributed to cuerda seca. The use of black line for separating coloured glazes in Iran, as
showed in this thesis, has a history much longer the history of cuerda seca. Hence, I have finally
suggested that cuerda seca is an inappropriate term to cover the seventeenth century Persian polychrome
tiles. The term ‘haft rang,’ which is used for nominating the antecedents of the seventeenth century
polychrome tiles, is preferred in this thesis as this term is also widely used in today’s Iran to address this
type of polychrome tiles.

Full textAbstract:
The natural capacity of DNA for molecular self-assembly has already been exploited to create DNA based tiles which can self-assemble into nano-scale arrays and carry out nano-scale computation. Thus far, however, all such self-assembly has been passive, in the sense that the binding capacities of a tile are never altered throughout the assembly. The idea of active tiles, tiles that can send signals to each other and activate latent binding sites, has been proposed but never incorporated into a formal model. Here, I present an extension of the existent abstract tile assembly model by defining an active tile assembly and give a detailed example of an aperiodic set of active tiles which hierarchically produces a self-similar L-shape tiling. This yields a technique utilizing active tiles for the assembly of aperiodic self-similar shapes.

Doutoramento em Engenharia CivilO principal objectivo deste trabalho foi sistematizar características físico- químicas dos azulejos para conservação e restauro de fachadas azulejares da cidade de Ovar, pertencentes à fase produtiva da semi-industrialização e industrialização dos finais do século XIX inico do século XX, de forma a produzir réplicas técnicas para recolocação nos locais de fachada com lacunas de azulejo. Além de se ter criado uma base de dados sobre estes materiais, formularam-se réplicas para os corpos cerâmicos calcários e pó de pedra, sugerindo matérias-primas e grau de moagem para a sua formulação, pressão de prensagem, ciclo e temperaturas máximas de cozedura conferindo-lhes características técnicas para que estas possam ser aplicadas lado a lado com os azulejos seculares, sem que perturbem a unicidade técnica da fachada. Investigaram-se duas das patologias mais recorrentes que afectam o vidrado: destacamento por cristalização de sais e fendilhamento. A primeira afecta a perda da parte pictórica do azulejo, atirando-o para uma remoção compulsiva da fachada aquando da sua intervenção para conservação restauro. A segunda permite-nos compreender possíveis compromissos técnicos feitos no passado.
The main objective of this work was to systematize physic-chemical characteristics of tiles removed for conservation and restoration of façades in the city of Ovar, belonging to the productive stage of semi industrialisation and industrialisation in late 19th century beginning of 20th century, in order to produce technical replicas to be used in façades gaps. Besides creating a database on these materials with an inexistent extension in Portugal, it was also achieved the lab production of replicas for ceramic bodies of calcitic tiles and pó de pedra, suggesting raw materials and its particle size, pressing pressure, maximum temperatures and firing cycle, assuring technical characteristics so that they can be applied alongside the secular tiles without disturbing the technical harmony behaviour of the facade. Two of the most recurrent pathology affecting the glaze were investigated: glaze detachment promoted by salts crystallization and crazing. The first affects the loss of the tile waterproof decoration, throwing it to a compulsory removal of the facade at its intervention for restore and conservation. The second allows us to understand possible technical commitments made in the past.

Full textAbstract:
This thesis is concerned with the problem of colour shade grading for Industrial Inspection and attempts to find accurate and robust solutions to this problem. The application we are interested in, is the automation of the ceramic tiles manufacturing process so as to replace the human inspectors responsible for the quality control of the product. Therefore our aim is to perform the colour grading in a way which is consistent with what the human experts and subsequently the clients would perceive. First an overview of colour vision, colour measurement and colour constancy is given. Then a method that tackles the problem of colour grading of uniform and patterned surfaces is proposed. This method is the first step towards colour grading since it involves various corrections of the data, so as to provide the necessary precision for any further attempt. The problem of colour grading of random textures is then addressed. A method based on the comparison between colour histograms is proposed, and various statistical aspects involved in the comparison of distributions such as the colour histograms are discussed. Since the real-time implementation of any industrial inspection method should be taken into account, we use a space-effective method of storing colour histograms. Having solved the problem of colour grading for the majority of uniform and textured surfaces, we then try to optimise the performance of the proposed techniques, for cases where it fails. We attribute that to the fact that every electronic sensor captures colour and patterns in a way which only approximates what the human vision system would perceive. First we propose a method of perceptual colour grading of uniform surfaces, which transforms the camera data to data as they would have been recorded by the human eye. This method makes use of metameric data, to determine the relation between the human and the electronic sensors. We use various methods of generating metamers, and we show how the need of a spectrophotometer can be overcome. In a similar way, we propose a method of perceptual colour grading of random textures, which involves the restoration of the electronically acquired data and then their transformation to a colour space which expresses the way we perceive colour texture. We test both methods with real data, and we compare them with the non-perceptual ones. All the methods proposed in this thesis have been tested with real data, from the ceramic tiles manufacturing industry, previously colour graded by human inspectors. The consistency of the methods has been tested by using various sets of all sorts of tiles, and by repeating the acquisition and grading processes many times for every set of tiles. Further, these experiments have been carried out using different apparatuses, thus allowing us to draw conclusions about their quality and to make our methods as hardware independent as possible.

The aim of this study is to examine the technology of the relatively deteriorated historic tile, brick and mortar samples of Sivas Gök Medrese and Tokat Gö
k Medrese. Their main deterioration factors were analyzed mainly as salt weathering. It was examined in detail, and the possible desalination methods were discussed. For this purpose, the studies were carried out with a field survey and laboratory experiments on the two sites. Documentation of visual decay forms of Tokat Gö
k Medrese were done with AutoCAD. The density and porosities of tile body and mortar samples were determined by using RILEM standards. The pore size distributions of tile and mortar samples were examined by Mercury Intrusion Porosimetry. Modulus of elasticity of tile body and mortar samples was determined and compared with the other Seljuk building materials. Mineralogical compositions of the tile body and glaze, adhesive tile mortars of Sivas Gö
kmedrese and Tokat Gö
kmedrese were analyzed with X-Ray Powder Diffraction (XRD). Their microstructure and chemical compositions were determined by using Scanning Electron Microscope coupled with Energy Dispersive X-Ray Spectroscopy (SEM-EDX). The salts were determined for various methods such as spot tests and XRD analyses. The possible treatment methods of salt crystallization were discussed according to the properties of the examined samples. One of the most essential causes of decay factor was salt crystallization for the two buildings which causes detachment and loss of tiles. The deteriorations were distributed over the upper and lower sides of the wall which were close to the dampness zones from the roof and above ground. The experiments proved different kinds of salts such as thenardite, sylvite, halite, natrite, nitratine and niter coming from the ground and the restoration materials such as cement based mortars. The relative humidity of the environments was compared with that of salt characteristics. It was proved that the tiles were adversely affected from salt crystallization. The best desalination method was discussed. Advection method by using poultices was based on the transformation of ions through the flowing moisture. The most prominent characteristic of the poultices must have smaller pore size distribution than original salty materials. The pore size distributions of the tiles and gypsum mortars were determined to compare and chosen the best poultice from the literature. It was concluded that kaolin-sand-based poultices having known properties was the best one as considering the pore size distribution of the tiles and mortars. The study on material properties and desalination process was expected to help different monuments having salt problem.

Full textAbstract:
Glazed tiles were used by the Lodhis and Mughals to embellish their buildings in northern India from the late fifteenth to seventeenth century. Tile-work from this region and period is understudied, particularly on matters related to its origin and technology. This thesis presents findings of a research undertaken on a series of tiled buildings located at Delhi, Agra, and Punjab in northern India, from the period of Lodhi and Mughal rule. Tile samples from the buildings have been scientifically analysed - mainly using scanning electron microscopy with energy dispersive spectrometry, and electron microprobe microanalysis with wavelength dispersive spectrometry - for their characterisation. Ethno-archaeological studies on related traditional craft industries have been used to build a more accurate rendition of the technologies employed in their manufacture. A field survey of in situ tile-work has been used to correlate stylistic and physical attributes with data determined through analyses. Results from the study show that different methods were utilized for the production of tiles at Delhi/Agra and Punjab. Those of the Delhi type have indigenous features in their technology, while the Punjab specimens are shown to be technologically closer to those from the core Islamic lands. The industry at Delhi is further shown to have evolved locally, developing gradually from the Lodhi to Mughal period, while the Punjab tile industry at the time of the Mughals is demonstrated to be an import, its establishment clearly influenced externally, with the sudden appearance of a new technological style. The tile-work at both places is however determined to be of the same basic character as Islamic tile-work of the stonepaste variety. This study, besides presenting a comprehensive picture on Lodhi and Mughal tiling traditions, provides important new information in the discipline of Islamic ceramic studies, particularly on the development of stonepaste technology and its transfer.

Full textAbstract:
Product visual inspection is still performed manually or semi automatically in most industries from simple ceramic tile grading to complicated automotive body panel paint defect and surface quality inspection. Moreover, specular surfaces present additional challenges to conventional vision systems due to specular reflections, which may mask the true location of objects and lead to incorrect measurements. Some sophisticated optical inspection methods have already been developed for high precision surface defect inspection in recent years. Unfortunately, most of them are highly computational. Systems built on those methods are either inapplicable or costly to achieve real-time inspection. This thesis describes an integrated low-cost intelligent system developed to automatically capture and extract regular defects of the ceramic tiles with uniformly colored specular coatings. The proposed system is implemented on a group of smart cameras using its on-board processing ability to achieve real-time inspection. The results of this study will be used to facilitate the design of a robust, low-cost, closed-loop inspection system for a class of products with smooth specular coatings. The experimental results on real test panels demonstrate the effectiveness and robustness of proposed system.

Este trabalho apresenta uma revisão bibliográfica a respeito dos rejuntes para revestimento cerâmico. A nomenclatura internacional é explorada e os tipos de rejunte e seus empregos são enumerados. Para embasar o leitor sobre o reves-timento cerâmico, os principais conceitos a ele relacionados são exibidos de forma sucinta. Uma vez que o rejunte é um componente importante do revestimento ce-râmico, suas funções dentro desse subsistema são abordadas em detalhes. O as-pecto de alívio de tensões é amplamente comentado, uma vez que essa é uma função essencial do rejunte, particularmente no caso de fachadas. Ao final, são abordados os aspectos de preparo e aplicação dos rejuntes, particularmente os produtos cimentícios. O rejuntamento de locais específicos, como encontros com selantes e interfaces com aparelhos sanitários são detalha-dos com vistas à diminuição da ocorrência de manifestações patológicas futuras. No trabalho experimental, painéis em forma de laje revestidos com placas cerâmicas são submetidos à flexão até a ocorrência de desplacamento, objeti-vando detectar qual a influência da largura da junta e do tipo de argamassa ade-siva na ruptura do corpo-de-prova. Os resultados indicam que a largura das juntas de assentamento assumem importância apenas quando a argamassa adesiva apresenta alta resistência de aderência.This study presents a bibliographical revision regarding the ceramic tile grouts. Here, the international nomenclature is explored and the types of grouts as well as its employments are enumerated. To base the reader on the ceramic tile cladding, its main concepts are shown succinctly. Being the grout an important component of the ceramic tile cladding, its functions in this subsystem are broached in details. The aspect of stress relief is widely mentioned, for this is an essential function of grout, particularly in the case of facades. In the end, the aspects of the preparation and the application of grouts are broached, particularly the cementitious products. The grouting of specific places such as meetings of sealants and interfaces with sanitary devices is detailed viewing the decrease of the occurrence of future problems. In the experimental study, panels in flagstone form tiled with ceramic plates are submitted to flexion until the occurrence of rupture of these panels, aiming to detect the influence of the joint thickness and of the type of the adhesive mortar in the rupture of the sample. The results indicate that the nesting joint thickness only assumes importance when the adhesive mortar presents high resistance of adherence.

Syfte: Att genomföra en fallstudie av hur försörjningskedjor i byggkeramikbranschen har arbetat med SCRM-processen innan och under COVID-19 pandemin, samt att skapa en SCRM-process som är specificerad för byggkeramikbranschen. Frågeställningar: Hur har arbetet med SCRM-processen sett ut i återförsäljarens försörjningskedjor innan och under COVID-19 pandemin? Hur skulle en SCRM-process specificerad för byggkeramikbranschen se ut? Genomförande: Genom intervjuer med respondenter från flera aktörer i återförsäljarens försörjningskedjor samlades empiri så att arbetet med SCRM-processen innan och under COVID-19 pandemin kunde kartläggas. Empiri samlades även in från en branschexpert och från försörjningskedjornas aktörer till den andra frågeställningen. Därefter gjordes förslag till en sårbarhetskarta, en riskbedömningsmatris och en riskhanteringsmatris för byggkeramikbranschen, som slutligen sammanfattades till en SCRM-process specificerad för byggkeramikbranschen. Slutsats: Arbetet med SCRM-processen innan COVID-19 tycks inte ha skett i återförsäljarens försörjningskedjor, men alla studerade aktörer har använt sig av SCRM-processen i olika mån under COVID-19, varav återförsäljaren har arbetat mest och leverantörerna arbetat minst med SCRM-processen. En SCRM-process specificerad för byggkeramikbranschen har skapats och har sammanfattats både i text och i figur, där specifika verktyg och branschspecifika aspekter har rekommenderats. Nyckelord: SCRM-process, byggkeramikbranschen, byggkeramik, COVID-19.Title: The SCRM process in the ceramic tiles business: before and during COVID-19 and forward Researchers: Alison Karlsson & Ellen Wiss Gullberg Examinator: Peter Berling Supervisor: Helena Forslund Background: The ceramic tiles business has turned out to be an unstudied business with many literature gaps, among others in relation to the SCRM process and to the COVID-19 pandemic. Purpose: To do a case study of how supply chains in the ceramic tiles business have worked with the SCRM process before and during the COVID-19 pandemic, and to create a SCRM process that is specified for the ceramic tiles business. Research questions: How has the work with the SCRM process looked like in the reseller’s supply chains before and during the COVID-19 pandemic? What could a SCRM process specified for the ceramic tiles business look like? Method: Through interviews with respondents from many of the actors in the reseller’s supply chains, empirical data was collected so that the work with the SCRM process before and during the COVID-19 pandemic could be mapped. Empirical data was also collected from a business expert and from the supply chain actors to the second research question. Thereafter a suggestion for a supply chain vulnerability map, a risk assessment matrix and a risk handling matrix for the ceramic tiles business was created, which was finally summarized to a SCRM process specified for the ceramic tiles business. Conclusion: The work with the SCRM process before COVID-19 seems to have not existed in the reseller’s supply chains, but all of the actors of the supply chains that were studied have used the SCRM process in different degrees during COVID-19, where the reseller has worked the most and the suppliers have worked the least with the SCRM process. A SCRM process specified for the ceramic tiles business has been created and has been summarized both in text and in figure, where specific tools and business specific aspects have been recommended. Keywords: SCRM process, ceramic tiles business, ceramic tiles, COVID-19.

Abstract
It was in the first decade of the twentieth century that the first white china Factory was implemented in Brazil. Fruit of the association between the Sao Paulo Aristocracy and the Italian Romeo Ranzini, this factory was responsible for producing significant amounts of crockery in industrial moulds in sao Paulo, Brazil. It was also the first factory to produce decorative tiles that would be part of the architecture of the public buildings built between 1919 and 1922 in Commemoration of the Centennial of the Brazilian Independence. Known as The Santa Catharina Factory, this factory was inaugurated in 1913 with the participation of Italian immigrants and German technologies for the development of its first manufacturing activities. As a result of a number of economic, political and social matters that started in the previous century in the city of Sao Paulo, The Santa Catharina factory played an important role in industrial development as regards the production of national white china and was used as a model for the construction of new ceramic factories in Sao Paulo. After acquired by Matarazzo industries in 1927, had closed their activities in 1937. This research is based on the identification and analysis of the first tiles produced in Brazil by the Santa Catharina Factory, which were part of the architectural decorations of the buildings built in Sao Paulo to the celebration of the Centennial of the Brazilian Independence. Designed by Victor Dubugras, The Largo da Memoria (located in the city of Sao Paulo) and the buildings located in the "Paths of the Sea" road marked the beginning of Brazilian industrialization and the emergence of Neocolonial Movement in architecture of Sao Paulo. Studies of the first national patterns of decorative tiles approach a subject poorly researched by experts in tiled studies in Brazil, although in this case these tiles have represented not only an important milestone in the national industrialization, but also have demarcated the significant changes in architectural and decorative practices in the country in the early twentieth century; RESUMÈ:
C'est durant la premiere decennie du XXe siecle que la premiere usine de porcelaine blanche fut implant& au Bresil. Elle fut le fruit de l'association entre l'aristocratie de Sao Paulo et l'italien Romeo Ranzini. L'usine produisait une quantite signifiante de porcelaine sur le territoire industriel de Sao Paulo. Ce fut egalement la premiere usine a produire des carreaux decoratifs qui sont aujourd'hui visibles dans l'architecture des batiments publics construit entre 1919 et 1922, pour la commemoration du centenaire de l'independance bresilienne. Connue sous le nom de Santa Catharina, cette usine fut inaugure en 1912. Elle fut construite par des émigrés Italiens, et utilisa pour la technologie allemande pour so production. En tant que resultat d'un certain nombre de questions economiques, politiques et sociales qui ont &butes durant le siecle precedent dans la ville de Sao Paulo, l'usine Santa Catharina a joue un role important dans le developpement industriel de la production de porcelaine blanche nationale et a ete utilise comme modele pour la construction de nouvelles usines de ceramique a Sao Paulo. Apres avoir ete achete par l'industrie Matarazzo en 1927, elle cessa ses activites en 1937. Cette recherche est basee sur l'identification et l'analyse des premiers carreaux decoratifs fabriques au Bresil par l'usine Santa Catharina, qui etait une partie des decorations architecturales des batiments construits a Sao Paulo pour la celebration du centenaire de l'Independance Bresilienne. Connue par Victor Dubugras, le "Largo da Memoria" (situe dans la ville de Sao Paulo), et les batiments situes sur le "Path of the Sea", ont marque le debut de l'industrialisation bresilienne et l'emergence d'un mouvement neocolonialiste dans l'architecture de Sao Paolo. L'etude des premiers modeles nationaux de carreaux decoratifs est un sujet peut etudie par les experts bresiliens, bien qu'ils furent un jalon importante pour l'industrialisation nationale. Its ont egalement entrains des changements importants dans les pratiques architecturales, et decoratives au sein du pays au XXe siecle.

carreaux; RIASSUNTO: Nel primo decennio del Novecento vide luce la prima fabbrica di ceramica di porcellana in Brasile. Frutto dell'associazione tra l'aristocrazia Paulista e l'italiano Romeo Ranzini, questa fabbrica fu responsabile della produzione di notevoli quantita di ceramica di porcellana mediante stampi industriali nella citta di San Paolo, Brasile. Fu anche la prima fabbrica a produrre azulejos che avrebbero poi fatto parte dell'architettura degli edifici pubblici costruiti tra it 1919 ed it 1922, per la commemorazione del Centenario dell'indipendenza Brasiliana.
Conosciuta come Fabbrica di Santa Catharina, questa fu inaugurata nel 1913, con la partecipazione di immigrati italiani e con l'impiego di tecnologie tedesche per lo sviluppo delle sue prime attivita produttive. Risultato di una serie di cambiamenti economici, politici e sociali, che ebbero inizio nel secolo precedente nella citta di San Paolo, la Fabbrica di Santa Catharina svolse un ruolo importante nello sviluppo industriale per quanto riguarda la produzione di ceramica di porcellana nazionale e fu adottata come modello per la costruzione di nuove fabbriche a San Paolo. Successivamente, fu acquisita dalle industrie Matarazzo nel 1927, vedendo poi chiudersi le sue attivita nel 1937.
Questa ricerca si basa sull'identificazione e l'analisi dei primi azulejos prodotti in Brasile dalla Fabbrica di Santa Catharina che fecero parte delle decorazioni architettoniche degli edifici costruiti a San Paolo per la commemorazione del Centenario dell'indipendenza Brasiliana. Progettati da Victor Dubugras, it Largo da Mem(Via (situato nella citta di San Paolo) e gli edifici che si trovano nei Caminhos do Mar marcarono l'inizio dell'industrializzazione brasiliana e la nascita del Movimento Neocolonial dell'architettura Paulista. Gli studi dei primi modelli di azulejos nazionali affrontano un argomento poco studiato dagli esperti in azulejaria in Brasile, nonostante rappresentino un importante avvenimento dell'industrializzazione nazionale, ma segnano anche i cambiamenti di significative pratiche architettoniche e decorative nel Paese nel primo Novecento.

Full textAbstract:
The ten rectangular red clay tiles which comprise the collection known as the "Tring Tiles" depict stories from the apocryphal Infancy of Christ Gospels and are dated to before the second century. The eight tiles held at the British Museum and the two tiles and fragments at the Victoria and Albert Museum are believed to be the remains of a longer series which were mounted as a wall frieze in Tring Parish Church. The images on the tiles portray Jesus, from ages three to eight, performing miracles of killing and revival, trickery, and acts of charity. The final tile depicts a wedding feast similar to the feast at Cana. Explanation for the placement of these tiles, produced with a rare technique and containing unusual portrayals of Jesus, in a parish church, is dependent upon the examination and interpretation of religious and social perspectives in early fourteenth-century England.

Em Pernambuco, azulejos portugueses dos séculos XVII e XVIII estão presentes em vinte edificações religiosas. Neste período, em Portugal, houve modificações na organização produtiva dos azulejos, objetivando adaptar-se às demandas de épocas distintas. Esta pesquisa busca compreender se tais modificações promoveram variações na caracterização tecnológica destes azulejos históricos. Foi realizado o levantamento de danos dos azulejos deste período, constatando-se uma baixa qualidade das peças pertencentes à primeira metade do século XVIII, em consequência da alta demanda existente. Os azulejos desta fase são os mais abundantes e apresentam os mais elevados índices de patologias, quando comparados às duas outras fases azulejares. Além da caracterização tecnológica através do levantamento de danos, amostras de azulejos setecentistas foram submetidos às análises química e mineralógica. Os ensaios de caracterização física são destrutíveis, e como as peças históricas não podem ser mutiladas, realizou-se a reprodução tecnológica do corpo cerâmico destas peças, com base na composição identificada através das análises e utilizando-se de técnicas da manufatura tradicional. A caracterização da tecnologia dos azulejos históricos realizada neste trabalho reforça os estudos no âmbito do conhecimento técnico do azulejo, fornecendo subsídios para profissionais da área de conservação do patrimônio material possam intervir com materiais e métodos adequados, preservando assim este bem cultural.
In Pernambuco, there are Portuguese tiles from the seventeenth and eighteenth centuries in twenty religious buildings. During this period, in Portugal, to meet the demands of different times, there were changes in the production process of these tiles. This research seeks the understanding of whether such changes cause variations in technological characterization of these historical tiles. A field research was conducted to analyze the damage in these Portuguese tiles, and there was noted that there is a low quality of parts belonging to the first half of the eighteenth century, because of the high demand existent in that period. The tiles of this period are the majority, and have the highest rates of damage compared to tiles from other two periods. Besides the technological characterization obtained through the field research, samples of these eighteenth-century tiles were submitted to chemical and mineralogical analyzes. Physical characterization tests are destructible and, as historical items cannot be damaged, a reproduction of the ceramic body of these parts had been performed, based on the identification of its composition and manufacturing techniques. The characterization of the technology of the historical tiles performed in this work reinforces the studies regarding the specialized knowledge of historical tiles, providing support to professionals of specialized areas to intervene with appropriate materials and methods, thus preserving this cultural asset.
