Description: | Incomplete copper alloy fragment from a casting jet of probable later prehistoric or Roman date (200 BC - 400 AD). The fragment is irregular in shape with a single domed (D shaped cross section) oval from which two sub-rectangular tapered pointed runners extend. Both these runners are irregular and incomplete a third similar shaped runner has been lost and a small stub can be seen on the oval base. The fragment represents a rare survival of the casting process, being the discarding remnants from the mould. The artefact cast using this method is likely to be relatively large as three runners were used to carry the molten metal into the mould. Dr Peter Northover has suggested that the date for this casting jet is after the Bronze age as it doesn't match the casting residue that he has seen, he also suggested it was unlikely to date from the early Iron Age, suggesting a possible Roman date. The casting jet measures 36.5mm length, 21.9mm width and is 20.3 thick; it weighs 17.8 grams.
