Two irregular shaped lumps of copper alloy metal working slag. Frequent small pits are visible in the surface of both lumps but are most prominent on one side of each. The other side of each lump has globular protrusions and occasional larger less defined pits. There is a coating of light green powdery oxidisation (verdigris) over much of the surface of both sides with patches of bright copper coloured metal showing.
