ASSESSMENT OF METALWORKING DEBRIS FROM THE CASTLE MALL EXCAVATIONS, NORWICH, NORFOLK
Author(s): Justine Bayley
About 130 kg of ironworking slag and 12 kg of copper-rich spillages and waste as well as several boxes of 'bell mould' were examined. These materials were concentrated in a few parts of the site. Although much of the ironworking debris was from the 10th-11th century contexts, there were significant amounts from later contexts which may not be residual. The Late Saxon material includes a small amount of tap slag as well as larger amounts of smithing slag, including hearth bottoms; the slag from later contexts is all smithing debris. There are a few Late Saxon crucibles but most of the copper-rich debris is associated with bell pits and comes from deposits dated to c.1250-1400. Further work is suggested to identify the nature of the copper alloys being worked at both periods and to attempt to resolve the date of production of the slags in the later context.
