AbstractThe history of the manufacture of the magnificent bronze castings produced in ancient China has been reinterpreted a number of times during the past hundred years or so. These bronzes were first believed to be fabricated by lost wax (cire perdue) casting, but this gave way to a belief that piece mold casting was the dominant, if not the sole method of manufacture from the Shang (1700-1100 BCE) until possibly as late as the Tang dynasty (618-907 CE). This has been reinforced by the finding, a number of years ago, of the Houma piece mold foundry, as well a number of more recent similar finds. However, this stance was challenged by the discovery of openwork bronze objects as early as in the 1920s, and more strongly challenged in the late 1970s by finds of intricately cast interwoven openwork bronze objects at the Tomb of the Marquis of Yi, dated to the Warring States Period (475-221 BCE). Since then many other similar bronze objects have been found. Questions exist concerning the very existence of the lost-wax process as early as the Spring and Autumn Period (771 to 476 BCE), and was it independently developed in China, or was it introduced from the outside.

In the 19th and early 20th centuries, Paris was home to scores of bronze foundries making it the primary European center for the production of artistic bronzes, or bronzes d’art. These foundries were competitive, employing different casting methods—either lost-wax or sand casting—as well as closely guarded alloy and patina recipes. Recent studies have demonstrated that accurate measurements of the metal composition of these casts can provide art historians of early 20th-century bronze sculpture with a richer understanding of an object’s biography, and help answer questions about provenance and authenticity. In this paper, data from 171 20th-century bronzes from Parisian foundries are presented revealing diachronic aspects of foundry production, such as varying compositional ranges for sand casting and lost-wax casting. This new detailed knowledge of alloy composition is most illuminating when the interpretation of the data focuses on casts by a single artist and is embedded within a specific historical context. As a case study, compositional analyses were undertaken on a group of 20th-century posthumous bronze casts of painted, unbaked clay caricature portrait busts by Honoré-Victorin Daumier (1808–1879).

SUMMARY Richly inflected languages often have morphologies in which one or two key relational morphemes serve as the glue which binds other, more substantive morphemes together. When an important relational morpheme suffers phonetic erosion, it may be replaced rather abruptly by a successor morpheme which obtains a foothold in the relevant paradigm and then spreads rapidly, replacing the old morpheme throughout the system. We will refer to this as the 'lost-wax' (cire perdue) method of formal renewal, on the analogy of an ancient method for casting bronze artefacts. The point is illustrated by a close case study of two morphemes, Inverse and Potential, connected with the pronominal agreement system of a set of closely related Australian languages. The mechanics are somewhat different in the two cases, but both can be described as variations on the lost-wax method. RÉSUMÉ Dans les langues à inflexion riche, il se trouve souvent que la morphologie possède un ou deux morphèmes relationnels qui servent à lier d'autres morphèmes à plus grande substance sémantique. Quant un tel morphème relationnel risque de disparaître à cause d'érosion phonétique, il peut se faire remplacer d'un coup par un autre morphème qui gagne une entrée dans le paradigme et puis s'étend rapidement jusqu'à occuper la même position relationnelle de l'ancien morphème. Nous proposons la métaphore de 'cire perdue' pour décrire cette méthode de renouvellement formel, par analogie avec une méthode classique de mouler les figures en bronze. Dans ce contexte nous étudions l'histoire de deux morphèmes, inverse et potentiel, dans le système de désinences personnelles d'un groupe de langues australiennes. Chaque cas présente une mécanique originelle, mais tout les deux rentrent dans le cadre général de la méthode 'cire perdue'. ZUSAMMENFASSUNG Sprachen mit reicher Inflexion haben oft eine Morphologie, in der ein oder zwei zusammenhängende Morpheme andere wesentlichere Morpheme zusam-menbinden. Wenn ein solches Morphem phonetisch zerfällt, kann es ein anderes Morphem plötzlich ersetzen und eine Stelle im Paradigma finden, von dem es sich im System schnell ausbreiten kann, indem es das alte Morphem im ganzen System ersetzt. Wir nennen hier diesen Vorgang 'verlorene Wachs'-Methode der formellen Erneuerung, als Analogie zur althergebrachten Methode der Gußform von Bronzekunstgegenständen. Wir illustrieren den Vorgang anhand einer Fallstudie von zwei Morphemen im pronominalen System der grammatischen Ubereinstimmung in einigen eng verwandten Sprachen Australiens.

AbstractThis study characterizes the bronze jewellery recovered from the Lusatian culture urn-field in Mała Kępa (Chełmno land, Poland). Among many common ornaments (e.g. necklaces, rings, pins) the ones giving evidence of a steppe-styled inspiration (nail earrings) were also identified. With the dendritic microstructures revealed, the nail earrings prove the implementing of a lost-wax casting method, whereas some of the castings were further subjected to metalworking. The elemental composition indicates the application of two main types of bronze alloys: Cu-Sn and Cu-Sn-Pb. It has been established that the Lusatian metalworkers were familiar with re-melting the scrap bronze and made themselves capable of roasting the sulphide-rich ores.The collection from Mała Kępa has been described in terms of its structure and composition. The investigations were made by means of the energy dispersive X-ray fluorescence spectroscopy (ED-XRF), scanning electron microscopy (SEM) coupled with an energy dispersive X - ray analysis system (EDS) and optical microscopy (OM). In order to fingerprint an alloy profile of the castings with a special emphasis on the nail earrings, the data-set (ED-XRF, EDS) was statistically evaluated using multidimensional analyses (FA, DA).

We have tried the experimental research of lost-wax casting to reconstruct Gilt-Bronze Pensive Bodhisattva; preliminary and reconstruction experiment based on ancient texts. Main object to reconstruct is Korean National Treasure No.83, Gilt-Bronze Pensive Bodhisattva (Maitreya), then we measure alloy ratio and casting method based on the scientific analysis. Other impurities were removed from the base metal components(copper : tin : lead) and their ratio was set to 95.5 : 6.5 : 3 where the ratios for tin and lead were increased by 2.5% each. The piece-mold casting method was used, and piece-mold casting experiments were carried out twice in this study but supplementary research on piece-mold casting was necessary. The microstructure was confirmed to be typical cast microstructure and the component analysis result was similar to that of the prior study. Analysis of the chemical composition is confirmed to copper, tin, lead, and zinc, and the chemical composition of the matrix was 87.8%Cu-7.5%Sn-2.7%Pb-2.1%Zn, and similar to previous experimental research. Also resulted in the detection of small impurity in Zn. Analysis of the mould revealed that the mould was fabricated by adding quartz and organic matter for structural stability, fire resistance, and air permeability. We expect that our research will contribute to provide base data for advanced researches in future.

The given article studies two small bells found in the tomb 19/2020 in the narthex of the single-nave church in block II at Eski-Kermen plateau. These bells have slightly flattened body with a slit and a small ball inside; they are decorated with corrugated transverse stripes. One of the bells is completely preserved, the other is fragmented. The aim of the work was to determine the composition of the metal and the manufacturing technology of the bells. The X-ray fluorescence analysis of the elemental composition of the metal of the bells showed that the items themselves and the ball inside one bell were made of tin-lead bronze. All currently known reconstructions of the manufacturing technology of such products are described, with the most possible one as the making of wax model of bells comprising of two halves and, later, lost wax casting; clay form was also lost.

AbstractThis paper adds a new interpretive layer to the already extremely well-investigated site of Demircihüyük, a small Early Bronze Age settlement at the northwestern fringes of the central Anatolian plateau. It presents a reassessment of the evidence for prehistoric mining in the region, as well as a new programme of chemical composition analysis integrated with an object functional and technological typology of the site's metal assemblages. The results reveal complex manufacturing techniques (such as bivalve mould casting, plating and lost wax) and the co-occurrence of several alloying types, including the earliest tin bronzes in the region. Object typology further indicates that the Demircihüyük community was at the intersection of two distinct metallurgical networks: one centred on the western Anatolian highlands, the other spanning the northern part of the central plateau. Additionally, several strands of evidence suggest that the beginning of interregional exchanges, linking central Anatolia to northern Levantine and Mesopotamian societies, may have started at an earlier date than the commonly assumed ca 3000–2800 BC.

The discovery in 1719, at Brough-on-Humber [North Humberside, SE 93 26], of a hoard of Late Bronze Age weapons and casting matrices is described from contemporary manuscript and printed sources. The subsequent passage of its component artefacts through antiquarian collections is carefully documented, and four pieces are recognized as surviving in the British Museum. These comprise two rare two-piece casting moulds together with one example of each casting product. One mould is a Welby, the other a Meldreth, type, formerly provenanced respectively to ‘Yorkshire’ and ‘Quantock Hills, Somersetshire’. All are described in detail and suggestions made as to the casting techniques in which they were employed. The hoard, possibly originally comprising more artefacts than were recorded, was accompanied by a spearhead, a socketed chisel and a tanged awl or spike, now lost. These are attributed to Burgess's ‘Ewart Park phase’ of LBA2, with parallels scattered throughout the north-east, east, south-east and south of England.

Dans une démarche pluridisciplinaire, qui emprunte aussi bien aux sciences humaines et sociales (archéologie, histoire des techniques, réexamen des textes anciens) qu’aux sciences chimiques (science des matériaux, métallurgie expérimentale, chimie analytique), cette recherche vise à reconstituer l’évolution des techniques de fonte à la cire perdue, depuis les plus anciens témoignages de son utilisation à Mehrgarh (Pakistan, 5e millénaire av. J.-C.) jusqu’aux premières grandes statues de bronze dans le monde égéen (fin du VIe, début du Ve s. av. J.-C.).L’étude des objets a parfois nécessité des développements analytiques spécifiques pour pallier à leur très forte altération, comme par exemple l’imagerie de photoluminescence synchrotron. Cela a notamment permis de reconstituer en détail la chaîne opératoire de fabrication de la rouelle de Mehrgarh, l’une des plus anciennes fontes à la cire perdue connue à ce jour. Sur la base de ces résultats, il est suggéré que la fonte à la cire perdue pourrait avoir été inventée pour donner la possibilité aux individus non métallurgistes de créer des objets importants en métal tels que ces amulettes, par le biais du façonnage d’un modèle en cire.Nous montrons que la cire perdue a ensuite été mise à profit pour donner naissance à une nouvelle forme de sculpture, la statuaire de métal. Au prix de parois très épaisses et d’assemblages mécaniques, nous mettons en évidence une première période de production de grandes statues en Mésopotamie pendant la deuxième moitié du 3e millénaire av. J.-C. Après un long hiatus, la grande statuaire métallique renaît de façon spectaculaire pendant la première moitié du 1er millénaire av. J. C., à la fois dans les mondes égyptien, sabéen et égéen. Nous identifions deux innovations importantes responsables de cette renaissance : le procédé indirect et l’assemblage soudé.Des essais de coulabilité effectués en faisant varier la composition de l’alliage et le matériau du moule sont présentés dans la dernière partie de notre travail. En moule de plâtre et avec un fort préchauffage, une coulabilité exceptionnelle a été obtenue pour le bronze à fort taux de plomb, donnant pour la première fois une idée des conditions de coulée nécessaires à l’obtention des parois très minces souvent observées sur les grandes statues antiques
Following a multidisciplinary approach combining social sciences (archaeology, history of techniques, examination of ancient texts) and chemistry (materials science, experimental metallurgy, analytical chemistry), our research aims to reconstruct the evolution of lost-wax casting techniques, from the earliest evidence of its use in Mehrgarh (Pakistan, 5th millennium BC) to the first large bronze statues in the Aegean (end of the 6th, beginning of the 5th century BC).The archaeological artefacts under study have sometimes required specific analytical developments to overcome their very strong alteration, such as synchrotron photoluminescence imaging. This allowed reconstructing in detail the chaîne opératoire of the Mehrgarh wheel-shaped amulet, one of the oldest lost-wax castings known to date. Based on the results thus obtained, it has been suggested that lost-wax casting might have been invented to give non-metalworkers the opportunity to create important metal objects such as amulets by simply shaping a wax model.We show that lost-wax casting was afterwards used to create a new form of sculpture, namely metal statuary. At the cost of very thick metal walls and mechanical assemblies, this led to an early production step of large statues in Mesopotamia during the second half of the 3rd millennium BC. After a long hiatus, large metal statuary reappeared spectacularly during the first half of the 1st millennium BC, both in the Egyptian, the Sabean and the Aegean areas. We were able to identify two important innovations responsible for this renaissance: the indirect process and the flow fusion welding.Castability tests carried out by varying the composition of the alloy and the material of the mould are presented in the last part of our work. An exceptional castability was obtained for highly-leaded bronze in plaster mould and with a high preheating. For the first time some insights are thus drawn on the casting conditions necessary to obtain the very thin walls often observed on large metal statues during the Classical Antiquity

Metal objects were of great cultural significance in pre-Columbian Mesoamerica. Historical and archaeological evidence prove that these items were made by the process of investment casting, or "lost wax" casting, by which a wax model of the object is created, and a ceramic mold is built around it. The wax is melted out to allow for the pouring of the molten metal. Considerable research has focused on the alloy composition of these objects, and some research has been done on the ceramic molds, but little is known about the composition, source, and manufacture of the wax itself. This paper builds upon work by Michael Tarkanian and Dr. Elizabeth Paris, attempting to fill this gap in the literature. Spanish written accounts of ancient Mesoamerican casting processes mention that wax from stingless bees was mixed with copal, or tree resin, and used to form the models for lost-wax casting. Waxes from Mexican stingless bees Melipona beecheii, Scaptotrigona pectoralis, and Melipona yucatanica were considered in this study, in addition to three copals: Bursera copallifera, Protium copal, and Pinus contorta. Thermal data from Differential Scanning Calorimetry revealed no changes in thermal behavior between waxes and their blends with copals, showing that none of the blends considered in this study are miscible. However, hardness testing revealed that the blends of Pinus contorta with Melipona beecheii and with Melipona yucatanica were harder than their respective waxes. This is in line with a Spanish account of the casting process, which mentions that copal was added so the wax may "[become firm and] harden well". Including data collected by Tarkanian and Paris, the most favorable material for investment casting would be Friesomelitta nigra wax mixed with Bursera copallifera, according to the criteria considered in this study.

The diploma thesis deals with the possibilities of using numerical simulation in investment casting technology. The first chapter of practical part deals with the use of simulations in the design of gating system for the shape-complex casting. At the same time, the practical part verified the accuracy of the simulation by test castings on which the X- ray inspection was performed. The results showed that the occurrence of internal defects predicted by simulation corresponded to the locations in the test casts. Next part of the thesis describes improvement of the use of liquid metal (so called “yield”) by numerical simulations. Two specific castings were chosen to perform simulation of current and newly designed variant of the gating system.

This diploma theses deals with possibilities of using numerical simulation for optimizing production of highly demanding thin-section casting produced by investment casting process. The casting made of aluminium alloy in which the manufacturing process was very problematic (occurrence of macro and micro shrinkages) has been chosen. By numerical simulation the existing technology has been analysed and based on this the possible reasons for defects found. This was later confirmed also by metallographic examinations. Following to this several options for a new technology were proposed and again by simulation checked their suitability. By comparing all above mentioned options two versions have been chosen in the end which was later tested in production with satisfactory results.

The purpose of this thesis is to assess the current state of production of ceramic shells in MESIT Foundry, a.s. and optimize it. The shells are evaluated in terms of their bending strength, gas permeability and microstructure. Subsequently, castings produced using the shells are evaluated with regard to number of non-conforming products and presence of defects. The final part seeks to compare different shells and outlines a possible new approach to the development of ceramic shells.

This chapter introduces the modern strategies that Medardo Rosso developed to reach an audience during his Parisian years. He worked mostly on a small scale and cast in his studio rather than having his sculptures cast by commercial foundries. He also began to exploit the new middle-class taste for cheaper sculptural materials, casting works in wax and plaster and selling them as finished pieces. He capitalized on his experience in Italian foundries, where the cire perdue (lost wax) method was regularly employed for casting bronzes, to generate special excitement around his sculptures. Rosso attempted to personalize his relationship with buyers and circumvent the Parisian gallery system that was becoming the intermediary between avant-garde art and a new bourgeois audience.

Abstract Traditionally investment casting of biomedical implants has utilized the lost wax process, this paper is an investigation into the possibilities of casting small lots of custom specific medical implants directly and indirectly from various rapid prototyping & tooling techniques. Small batch quantities for quick turn arounds cost and lead times are the main contributing factors for the purpose of this investigation. To directly produce parts means that a RP model will be used in the place of the wax pattern in the investment casting process. To indirectly produce parts means that a mould, which has been generated from RP&T techniques, will be used to manufacture wax patterns that will then in turn be used to investment cast the parts. The device to be manufactured is a non-sterile, referred to as ‘trial’ prosthetic implant. The implant is used by the operating surgeon to check the ‘fit’ of the cavity that will be made to receive the prosthesis plus bone cement that will be used to fix the implant in place.

Al2O3-SiO2 moulds have been adopted successfully as shell moulds for a single crystal casting for jet engine blades. Heavy-duty gas turbine blades also have large dimensions and complex features comparable to those of jet engines. Then shell moulds should be subjected to similar severe service conditions when casting heavy-duty gas turbine blades. Creep behavior of 90mol%Al2O3+10mol%SiO2, which was manufactured through the lost wax process by using fused Al2O3 powder (average particle size, 15 μ m), was studied at temperatures of 1450 to 1550 °C. in four-point bending creep tests. Creep deflection rates were linearly proportional to stresses. The proposed creep mechanism was Al grain boundary diffusion at the interfacial regions between Al2O3 stucco powder. No severe metal/mould reaction appeared for the region adjacent to the interface between moulds and Ni base superalloys.

Metal loss caused by selective leaching of aluminum (referred to herein as dealloying) in certain aluminum-bronze (Al-Brz) alloys is an environmentally-induced degradation mechanism in piping systems containing cast components exposed to marine, brackish, or raw water service. Examples of this form of degradation have been observed in ASME Code Class 3 Essential Cooling Water systems. Mechanical properties for tensile strength and fracture toughness of Al-Brz static and centrifugal castings, fabricated to ASME SB-148 CA952 and CA954 specifications, can locally degrade in service due to dealloying under long exposure to aggressive water environments. This paper presents the results on the reduction in mechanical strength as a result of dealloying. A mechanical testing program was completed where 20 tensile and 22 fracture toughness specimens were tested to determine the reduction in mechanical properties from no dealloying (virgin condition) to various amounts of dealloying up to 100% dealloyed condition measured across the specimen. The specimens were fabricated from components removed from service (some components being in service for over 25 years). The data were plotted as a function of percent dealloying where a systematic decrease in properties was seen directly dependent the amount of dealloyed material in the cross-section of the specimen.

Dentist, follow root canal therapy to treat teeth with pulpal involvement due to dental caries or as a result of trauma. In order to restore fractured and broken down teeth internal reinforcement is required in the form of a post-core restoration. The post extends into the root canal space and provides retention for the core, which subsequently helps to provide a foundation for the crown restoration. For the treatment procedure, post, core and crown are casted by an indirect procedure by taking the measurements from patient’s tooth in the form of impressions. These impressions are then converted into solid gypsum casts and then wax patterns are developed in order to facilitate casting by the lost wax technique. The final shape of the core and crown and success of the treatment entirely depends upon the skill of the dental technician and involves a number of variables in impressioning, cast poring and wax pattern fabrication. The treatment can be further simplified by making a prototype model of the post, core and the crown by taking the dimensions from the patient’s tooth. This paper presents four prototype models prepared from the solid model of the original tooth and three restored tooth.

Dealloying of aluminum-bronze (Al-Brz) is a potential environmentally-induced degradation mechanism in piping systems and components exposed to marine, brackish, or raw water service. Examples of this form of degradation have been observed in ASME Code Class 3 Essential Cooling Water systems. The degradation mechanism is loss of material due to selective leaching (i.e., dealuminification) due to localized corrosion. The dealloying occurs in the eutectoid phase in binary alloys; the eutectoid consists of α + β or α + β/γ2, and is dependent on aluminum content of the alloy, cooling rate during fabrication/welding, and the presence of a local crevice for the corrosion process to concentrate. Cast components are susceptible to general dealloying but unlike them, weldments of wrought pipe have not exhibited the same extent of degradation. The dealloying process leaves micro-voids in the microstructure within the eutectoid. Leakage (weepage) will occur once dealloying has extended through the wall thickness via a network of porous transformed phase. The dealloying process also causes a reduction in mechanical strength and fracture toughness properties. A detailed metallurgical evaluation has been completed to establish a fundamental understanding of the resistance of the pipe welds to dealloying that explains the better performance of the welds versus the castings. Factors affecting the dealloying susceptibility, such as aluminum and iron content, cooling rates during the solidification process, and the resulting microstructural differences were studied and evaluated. It was found that dealloying will not penetrate into the material unless a continuous network of susceptible microstructure is present. The difference in susceptibility between castings and weldments to dealloying was also determined. The findings of this comparative evaluation were significant and are being used in the aging management program to justify continued use of aluminum bronze piping welds for extended service for both above ground and below ground (buried) piping systems.
