  • ICP-AES comparative study of some Late Bronze Age hoards : evidence for low impurity bronzes in the Eastern Alps
    Trampuž Orel, Neva ; Drglin, Tatjana
    The chemical composition of ingots from eleven hoards in Slovenia and from onein Austria (the Styria region) from the Late Bronze Age were determined using the ICP-AES method and the total impurities ... compared. One hundred and twelve plano-convex copper ingots from the earlier LBA phase (12th-11th century BC or Ha A period) revealed, in analogy with contemporary bronzes alsoanalysed in our previous works, prevailing low concentrations of arsenic, antimony and nickel not exceeding 2%, with arsenic as the dominant impurity element. Conversely, in the later LBA phase (11th-10th century BC or Ha B period) totals of the same elements with cobalt included extend from 0.5% to almost 70%, with antimony as the dominant impurity element. The typical high concentration levels of impurities suggested that Fahlore deposits were used for smelting copper in the Ha B period, while chalcopyrite and other types of copper ores having low impurities were used in the earlier Ha A period. Both are typical of Eastern Alpine ore deposits.
