Metallurgical analysis of prehistoric material has hitherto been concentrated on examination of early artifacts, presumably made from newly-won metal, which may therefore contain trace elements to indicate the sources and trade-routes of contemporary metal supply. The present study was undertaken to discover whether bronze artifacts from the British Middle and Late Bronze Age, when an important component of the bronzes produced must have been re-used metal, show nonetheless perceptible variations in metal composition, which might correlate with changes of bronze types, or with the successive industries of the archaeological sequence.Analyses were made at the Research Laboratory for Archaeology in the University of Oxford, using an optical emission spectrometer. Samples of the bronzes studied were examined for the elements copper (Cu), tin (Sn), lead (Pb), arsenic (As), antimony (Sb), nickel (Ni), bismuth (Bi), iron (Fe), zinc (Zn), silver (Ag), gold (Au) and magnesium (Mg), the only elements found in the bronzes in appreciable quantities.
