CASTING WASTE
Unique ID: WAW-DBECC7
Object type certainty: Probably
Workflow
status: Awaiting validation 
An irregular fragment of copper alloy casting waste, of uncertain dating, but possibly Late Medieval to Early Post Medieval (1400 - 1800 AD).
The casting waste fragment consists of a sub rectangular sheet, with uneven, almost bubbly surfaces. It is sub rectangular in cross section. Two edges are smooth and unabraded, indicative of a fairly recent break.
It is a mid grey colour, with a couple of areas which display a distinctive shiny sheer to it. This shiny sheer is suggestive that the copper alloy has a high tin content. The weight of the fragment is suggestive that lead was used as part of the alloy composition as well.
It measures 37.08mm in length, 31.45mm wide and 7.51mm thick. It weighs 26.6 grams.
Fragments of casting waste like this one are hard to date confidentially. It is possible that it is part of the waste from the production of cast copper alloy cooking vessels, and therefore could be Late Medieval to Post Medieval dating (1400 to 1800 AD), but it could date to an earlier or later period. Scientific analysis of the elemental composition of the copper alloy would allow a more accurate date to be suggested.
