Description: | Copper alloy (bronze) casting waste of uncertain date; most probably post prehistoric (50 - 1700 AD). This fragment is from the neck (funnel / well) of a composite, probably two part, mould. The casting waste is conical; being oval in plan and D shaped in cross section. In profile the edges of the waste taper relatively evenly. This conical well descends into a rectangular runner with a rounded and abraded terminal. The sides show some evidence of casting seams although they are also similarly abraded. At the junction between the well and runner is an irregular D shaped transverse band; which is more evident on one face. The purpose of this band is unclear - most likely to do with the type of mould. The upper surface is pitted and rough, although heavily patinated. The casting waste is a mid green colour with an abraded and corroded thick patina that covers all surfaces. Casting waste is very hard to date in isolation but the patina and form might suggest a Roman or medieval date. A direct comparison has not been found. The survival of casting waste is relatively rare as it is usually recycled swiftly as a bi-product of casting.The casting waste measures: 22.3mm length; the top of the well measures18.1mm wide and 15.0mm thick; the runner measures 5.7mm and is 3.8mm thick. The waste weighs 7.44 grams. | Publisher: | http://finds.org.uk | Source: | Portable Antiquities | Identifier: | http://finds.org.uk/database/artefacts/r... | Go to resource |
