Description: | Lump of solidified copper which had developed a green patina. It is plano-convex (convex on one side and flat on the other). The convex side is irregular as is the outline while the flat side has various ripples which appear to have formed in a firmer 'skin' on top of a molton base as it cooled and contracted. This implies that the molten copper was formed in the bottom of a large curved based structure, probably a furnace rather than a the usual small crucible. This could have been during smelting or during reworking. It is not as highly domed as conventional bronze age ingots and therefore the date of the metal is uncertain; it could be Bronze Age to Medieval. It is 112.2mm long, 59.9mm wide and 15.5mm thick; it weighs 442 grams.
