Metalworking Ceramics

This paper outlines the range of ceramic finds, and their specific attributes, which provide evidence for the metallurgical processes that were carried out in medieval Britain. These are mainly crucibles and moulds associated with the working of copper alloys, gold and silver; evidence for lead, tin and pewter working is much rarer, while the only ceramics associated with iron-working are vitrified clay hearth linings. A typology of Late Saxon and medieval crucibles is presented, together with details of related forms such as cupels for the refining of precious metals, parting vessels and distillation vessels, and the technology of moulds. The potential of these finds for scientific analyses and further research is also summarised.
