County: Northumberland

Copper alloy tap slag measuring 66.10mm long, 36.19mm wide, 11.85mm thick and weighing 62.1g. The slag is very long and thin with rounded edges and evidence of air holes. One side is very flat and more smooth than the other, suggesting that the molten copper alloy was poured onto a flat surface where it then cooled.

Two pieces of iron slag, the larger measuring 187.9g, 61.62mm wide, 66.44mm long and 40.7mm thick. The smaller weighs 175.9g, 65.92mm wide, 68.20mm long and 45.14mm thick. They are both dark both dark brown in color, although covered in light brown dirty. Both are generally sub-circular in plain and section and have a very rough surface. The smaller of the two has some surface areas that are rounded which may indicate that it is part of a bloom or tap, but it is not clearly indicated.

A fragment of Iron bloomery slag. The fragment measures 41.42mm long by 29.63m wide and 14.31mm thick. It weighs 10.4 grams. The fragment of slag feels light for its size, and bears a resemblement to vitrified clay. Air bubbles are present. The process of smelting iron ore to produce iron has not changed much from the Iron Age to the Medieval period, so this piece of bloomery slag could date from any time between the Iron Age (800 BC) to the Medieval Period (1500 AD).

County: Oxfordshire

A large, roughly rectangular lump of bronze slag, airholes throughout and some elements of the raw copper sulphide are visible (a green-blue colour). The slag has a good deep green patina, similar to that seen on some local Bronze Age metalwork, so it may date from this period. If this lump of slag is indeed Bronze Age, it is interesting that it has survived and was not re-melted, as it is quite an amount of bronze.

A lump of lead cast-off from the manufacturing process. This material would have been removed from the surface of the molten metal, where the impurities rise during manufacturing. Although difficult to date, it is suggested that this slag could date from the Roman to Medieval periods. The slag fragment weighs 111 gms.

Cast-off from metal production, possibly copper. The film covering moltern metal within a crucible was often scrapped off and discarded (hence cast-off). This artefact weighs 2.5 gms and although it cannot be closely dated without contextual information, it may date to the Prehistoric periods as it was found in the vacinity of numerous lithic implements. Bronze Age - Medieval 2100 BC -1500 AD.
