From the conclusions:This paper presents the first global results from electron probe microanalysis of glass found in Hittite and early iron age contexts from sites in central Anatolia. The article considers the wide range of compositions discovered and poses the question whether the glasses were made in Turkey or not.

This data from Kaman-Kalehöyük illustrates that there was no ‘clean’ break in plant ash glass technology between the Late Bronze Age and the Early Iron Age in glasses found in central Anatolia, even though the late bronze age palatial civilisations and their economies collapsed c. 1100 BC leading to the development of smaller more localised polities. It is evident that there was a continuity in the production/ use of plant ash glasses as an alkaline flux but probably using slightly different raw material sources, perhaps as late as the 7th century BC.
2. It is premature to claim that the Hittites made their own glass using the scientific results provided here. If anything it can be tentatively suggested that the Hittite glass was fused in Mesopotamia. However, by using trace element and isotope analysis we will investigate this in much more detail. There are compositional hints that glass was fused from raw materials in Early Iron Age Anatolia but again this needs to be investigated with more sensitive analytical techniques. Both studies will form the focus of forthcoming papers.
