Historical research on the trade of metal supplies and objects often overshadows studies on the practices, recipes, and supplies of clays used by metallurgists of the time. Researchers in Belgium and France characterized metallurgical ceramic samples from the remains of a Late Medieval Period foundry in Brussels and found the analyses, in conjunction with written sources, highlight the mobility of clay materials, not just metal.
