Our research represents a case study in ancient metalworking to illuminate the challenges, processes, and both human and material agency behind these objects. We focus on copper alloy Hathoric loop sistra since these musical instruments are steeped in ritual and mythological connections to metalworking. Our work represents the early stages of our ongoing investigations...

A common theory is that copper smelting first appeared in the Near East in close connection with the early pottery industry. However, copper smelting may well have been discovered many times in history and at many places. Our hypothesis is that copper smelting could have been discovered when the copper-bearing mineral malachite, accidentally or intentionally, was present in lime-burning kilns...

Two metallurgical traditions coexisted in the Chalcolithic Southern Levant: the lost wax casting of polymetallic alloys and the pure copper technology. Details of their operational sequences are still unknown. To date, no production sites of lost wax casting technology have been found. Only the main steps of the pure copper technology can be reconstructed from the archaeological record...

The present study discusses the casting of copper axe-ingots in open, wet sand moulds, in an attempt to recreate porous artefacts that have been recovered in Brittany, France. The original axe-ingots are considered to be Irish copper metalwork from the Early Bonze Age. However, these artefacts are not finished objects and are poorly cast. This nevertheless appears to be deliberate because...

***Pyrgos-Mavroraki, an early 2nd millennium BC proto-industrial settlement, is an excellent case-study on which to apply experimental archaeometallurgy because it presents many different elements connected to the chaine-operatoire of copper metallurgy, typical of Early/Middle Bronze Age Cyprus...

***Artificially patinated copper alloys are found archaeologically in polychrome artefacts from the 19th century BC Egypt to historical and contemporary Japan. The unusual colour variations observed in these patinas, ranging from black to blue to purple, is due to a minor amount of gold (Au) and silver (Ag) in their copper matrix, whereas...

Bronze is an alloy of copper and tin, with lead also added. Hellenistic and Roman bronze objects have a variable percentage of metals, and because of this the colour of the alloy will differ depending on the proportions. The colour of the alloy can be maintained by polishing, but it is also possible to give a patina to the surface of bronze using a reagent...

***In the present paper an experiment made in north-western Iberia for producing bronze using local ores and similar techniques to those perhaps practiced by the ancient prehistoric metallurgists during Bronze Age is described...
