Glass ingots from the Uluburun shipwreck: Addition of glass cullet during manufacture and evidence for the changing context of New Kingdom Egyptian glass production in the late 18th Dynasty

Résumé

Our recent LA-ICP-MS analyses of glass ingots from the Uluburun shipwreck along with additional samples from Egyptian sites, primarily Amarna, encourage us to question how and where the ingots were produced. Because almost all the approximately 200 glass ingots are either greenish blue, colored by copper, or purplish blue, colored by cobalt, we focus here on these colorants and their attendant trace elements. Based on the evidence for copper and antimony in cobalt-blue glass, we conclude that the most likely explanation is the addition of glass cullet during ingot production, in accordance with suggested evidence from glassmaking texts thought to date to the Late Bronze Age. By comparing the Uluburun ingots with glass from Amarna using multivariate statistics and trace element ratios, we determine that while a few of the ingots might be consistent with Amarna manufacture, the great majority are not, but rather represent production from other workshops, probably following those at Amarna. The importance of these workshops is suggested by our finding that over half of the cobalt-blue Mycenaean relief beads for which trace element data is available were made with Egyptian glass closer to that of the Uluburun ingots than to glass found at Amarna.
