The liquation and drying process is used ta separate low amounts of si/ver from coppers, which spread in Europe at least from the 15th century onwards. Agricola was the first to describe extensively this new pro cess in Book J J of his De re metallica. Afew metallurgical treatises from modern times evoke it as weil, yet owing ta the lack of archaeo...

The ‘quimbalete’ is a kind of grindstone used notably in Potosi (Bolivia) during the Spanish conquest of South America. It was used to grind pieces of ore gravel from centimetric sizes to the size of sand. Its physical functioning, as well as the reason why this strictly Andean tool occupied a central place in a mainly European production chain, ha...

The originality of the Carolingian silver mines at Melle resides in the fact that they were completely opened by the use of fire. These mining networks provide the necessaiy material for an anthracological study. One of the twelve networks currently accessible has been studied in detail in order to determine the type of management and organisation...

L’essai des minerais a joué plusieurs rôles dans l’économie de la production minière, notamment à partir de la fin de la période médiévale. C’est à cette époque qu’ont été développées des techniques d’analyse opérant sur quelques grammes de minerai dans un four à moufle. Représentatif et reproductible, cet essai par voie sèche était utile à la gest...

Grâce aux apports combinés des traités métallurgiques et de chimie et de l’anthropologie, il est possible d’appréhender la question du passage du procédé d’analyse par voie sèche à celui par voie humide. Cette évolution, que l’on doit aux travaux de Gay-Lussac, a été motivée par une recherche de précision dans le dosage de l’argent des ateliers mon...
Article
Pour les médiévistes qui abordent la question de l’économie circulaire, la difficulté réside dans la capacité à rassembler des sources, écrites comme matérielles, au niveau de l’entreprise. Les résultats présentés ici sont le fruit d’une recherche de longue haleine à partir de documents rares. Dans ce contexte, l’étude se concentre sur les Pyrénées...

Full-text available
Pour les périodes anciennes, l’affinage de l’argent se pratique classiquement par coupellation. Il existe cependant d’autres procédés permettant d’obtenir un argent pur. En se basant sur une recette du début du XVIe siècle, nous montrons grâce à l’expérimentation archéologique la pertinence d’un traitement d’un alliage argentifère par ajout de verr...

Full-text available
L’alun est un matériau qui apparaît assez classiquement comme réactif dans plusieurs textes métallurgiques. Son identification sur le terrain, au sein d’ateliers métallurgiques, reste encore à démontrer. En revanche, il est possible d’organiser une réflexion autour de l’approche expérimentale afin d’apprécier autant le caractère opératoire que la n...
Article
The carbon content distribution of ferrous archaeological artefacts in a quantitative way allows us to understand the nature of the materials. Our previous works have ever proved that the use of laser-induced breakdown spectroscopy (LIBS) could be an efficient method to solve problems of in situ analysis and offer a high spatial resolution. To asse...
Article
Experimental archaeology was first theorised by Ascher in 1961 and then by Coles in 1973: it represents an important research methodology for the study of ancient technologies and societies. Since the 1990′s of the last century, the new concept of ‘experimental archaeometry’ appears in the wider field of archaeological science. Following this appro...
Article
When examining the alloy of several works of Adam Van Vianen, one of the founders of the Dutch Kwabstijl, with X-ray fluorescence (XRF), a more elevated silver and lower bismuth percentage than commonly found in works of his contemporaries was detected in the silver alloy. We hypothesize that Van Vianen used an alloy with a high percentage of silve...
Article
The excavation of the copper cementation workshop “Le Clos-Paul” in Charleville-Mézières (Ardennes, France), executed by the Cellule d’archéologie du Conseil départemental des Ardennes, led to the finding of fragments of coinage moulds. Dating from the middle of the 3rd century AD, they are the only evidence of an opportunistic production of counte...
Article
Field experiments in copper smelting were carried out in order to test assumptions about the copper production processes employed at the Vilabouly Complex (VC), an Iron Age extraction and production site in central Laos. VC is one of only three primary production sites known in Southeast Asia and appears to be a major copper production and mining l...

Au moment où la Jeanne Élisabeth fait naufrage, l’argent du Nouveau Monde se diverse en Europe depuis plus de 200 ans. Parmi les plus de 3 700 réaux de 8 et de 4 retrouvés dans sa cale, un atelier se distingue particulièrement car non seulement il signe l’origine de la plus grande part des monnaies mises au jour, mais surtout il a été installé au p...
Chapter
Métaux, pierres et autres matériaux de construction, roches nobles, bois, textiles, cuirs, sel, matières tinctoriales, etc., les matières premières, brutes ou issues d’une première phase de transformation, n’ont pas été peu nombreuses, dans l’Antiquité et au Moyen Âge, à circuler sur des petites et moyennes distances, quand elles n’ont pas entrepri...

Article
Research in both South America and Europe in a diachronic perspective allowed to bring together a series of examples relating to the use of a reverberatory furnace for smelting non-ferrous ores. Although the invention of this process may have occurred in multiple places, the main region of innovation is incontestably the Andes. To approach this dyn...
Article
The presence of carbon content is a key enabling factor in archaeological ferrous material studies because it can provide technological and temporal information on its fabrication. A strong relationship exists between the composition, the metallographic structure, and the mechanical properties of metals. Laser-induced breakdown spectroscopy (LIBS)...

Chapter
Although the term mineralurgy is very recent, it covers a technical reality that appears across ancient mining sites. It also embodies special-purpose dressing tools such as anvils, mallets and other ore grinders and cleansing structures, as well as sorting and residual waste rock pile locations. As of the fire-setting phase, ore dressing for smelt...
