A piece of copper alloy casting waste, metal working debris or slag of unknown period, Bronze Age to Post-Medieval in date (about 2000 BC - AD 1800). In shape, the waste is an irregularly shaped mass which is also irregular in section. The surface is rough and granular. There are some black inclusions and a brown rounded pellet. The waste has a mid green mottled patina. Measurements; length 43.9mm, width 41.7mm, thickness 11.4mm, weight 47.0g.

Three irregular fragments of copper metal working waste (slag) or fuel ash, of probable Roman to Post Medieval dating (c. AD 43 to AD 1800). The largest fragment is quite heavy, though the two smaller fragments are slightly lighter and appear to have the remains of silver in their mix. The process of working ore to produce copper or iron has not changed much from the Iron Age to the Medieval period. In addition these objects having been recovered from land producing objects ranging from the Roman through to the Post Medieval period, therefore these pieces of slag could date from…

Roman to Medieval period copper alloy slag. This object is a single piece of cast copper alloy slag, formed during the casting process. This was found alone, which makes it difficult to precisely date.

Three irregular fragments of copper metal working waste (slag) or fuel ash, of probable Iron Age to Late Medieval dating (c. 800 BC to AD 1600). The largest fragment is quite heavy, though the two smaller fragments are relatively light suggesting that minimal metal is present within the matrix.  The process of working ore to produce copper or iron has not changed much from the Iron Age to the Medieval period.

Eleven (11) irregular fragments of iron and copper metal working waste (slag) or fuel ash, of Iron Age to Late Medieval dating (800 BC to AD 1600). All three fragments are light for their size, which would suggest that minimal metal is present within the matrix. All have a honeycomb structure, formed of solidified air bubbles. All together the fragments weigh 80.0 g. The process of working ore to produce copper or iron has not changed much from the Iron Age to the Medieval period, so these pieces of slag could date from any time between the Iron Age (80…

A piece of what appears to be copper alloy slag. It has a high metal content and is very heavy for slag but seems too irregular for a finished piece. There are small bubbles in the piece and a rounded hollow seems to be the result of a large bubble. There is a loop at one end and a shaped tail at the other.

An amorphous piece of copper working slag, smooth yet curved on one side so possibly dripped (or scraped) from a crucible. Without contextual information it is impossible to date copper slag however noting its presence is important as it may indicate metal working.

Very irregular shaped lump of copper alloy metal-working residue. Very dense, very rough granular surface. Appears to be something that was soft rather than fluid when its shape was formed. Much of the surface is covered in a light green powdery oxidisation layer, but there are flecks of bright silver colour showing where high points have been scraped suggesting some silver content. Under magnification the surface is quite porous with frequent pitting visible. Appears to be the by-product of metal working in the area.

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.
