The principal aim of this thesis is the evaluation of the social significance of core-glass vessels in the Egyptian sphere of influence in the later New Kingdom, based on the technology, typology and distribution of the vessels. To assess the technology involved, the assemblage of manufacturing debris from Amanra was catalogued and examined. This material was then used to assess the potential techniques employed. The evidence suggests that a number of methods were used to form vessels, with trailing on, coating in powdered glass and press moulding, probable techniques. This was reinforced by an evaluation of the incidence of different colours of glass in this debris and their use as either background or decorative colours. X-ray examination of the internal structure of the vessels, while inconclusive, also supports the existence of a number of different techniques. Finally, contextual analysis of the debris from Amanra shows a close connection with royal activity. These points support the widely held suggestion, that core-glass vessel production was a royal monopoly. As a basis for typological studies, the vessel fragments from Amanra and Gurob were catalogued. There were two main areas of investigation. First, the evaluation of the vessels as chronologically sensitive. Both conventional stylistic analysis, following Nolte, and quantitative analysis based on the decorative features, show that the vessels are not good indicators of chronology. The second approach compares the vessels in terms of their attributes to vessels in other materials.
