Three fragments from ceramic moulds probably for copper working due to the presence of copper waste onsite.
One fragment has a surface with a straight edge and a rise with three faint parallel lines. Its fabric has a medium grey inner surface, margin and core, with patches of paler yellow on the outer surface.
The other two conjoining fragments have the impression of a flat surface and slightly curved edge, suggesting it was for casting a plain disc. Their fabric has a dark brown inner surface and core, with an orange outer surface.
From group G: Unillustrated/Undiagnostic Mould fragments.
