SEVENTEETH CENTURY COPPER ALLOY WORKING FROM HEAD STREET, COLCHESTER, ESSEX

Author(s): David Dungworth

Excavation at Head Street, Colchester revealed a number of 17th century pits cutting underlying Roman layers. At least one pit produced large quantities of ceramic mould; some of which appears to have been for the manufacture of bells while some appears to have been for the manufacture of cauldrons. Seven fragments of copper alloy and copper alloy slag were examined using a scanning electron microscope and energy dispersive spectrometer. The compositions and microstructures of the samples indicate the casting of a copper alloy rich in antimony. This alloy was not used for the manufacture of bells but was used for casting everyday objects, such as cauldrons. The ore(s) used to produce this alloy can be found in Britain and elsewhere, however, given the date, a source in Germany is most likely.
