DATING AND PROVENANCE OF GLASS ARTEFACTS EXCAVATED FROM THE ANCIENT CITY OF TALL ZIRA A, JORDAN

摘要

Fourteen glass objects recovered from excavations at the ancient city of Tall Zira'a, Jordan, were analysed using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to determine the period and origin of manufacture. The composition of glasses manufactured in the Late Bronze Age (LBA) and Iron Age are distinctly different, therefore major element analysis can be used to distinguish between the groups relatively easily. The LA-ICP-MS analysis provided quantitative trace element data which were used to determine the provenance of those glasses identified as LBA. This research discusses the implications of the presence of both Egyptian and Mesopotamian LBA glasses and examines the varying compositions and colour strategies employed in both the LBA and Iron Age objects. Specifically, glass in the LBA was considered to be one of the highest status items attainable, playing an instrumental role in diplomatic gift-giving. When considered with the archaeological information, the significance of these finds at Tall Zira.a indicates that this city was a settlement of high status, not primarily a convenient trading stop on the Transjordan route.
