Abstract:

This paper investigates the heat treatment of flint practiced at the Neolithic site of Hasankeyf Höyük in southeast Turkey. It does not involve petrographic or geochemical analysis to identify the physical and chemical evidence of heat treatment but aims to understand cultural aspects of the use of ancient lithic technology, using heat treatment as a case study. Heat treatment is a lithic production technique in which siliceous rocks are heated by controlled fire in order to improve their flaking quality. Archaeological evidence of heat treatment is seen all over the world, and numerous studies have contributed to the better understanding of this technique. However, what is particularly intriguing in the case of Hasankeyf Höyük is that there are many flint artefacts which were apparently overheated and unusable due to the frequent failure in achieving successful heat treatment. On the other hand, experimental studies using an electrical furnace and open fire show that once the appropriate heating time and temperature are learnt, the heat treatment of local flint at Hasankeyf Höyük is an easy process and does not require high technical skill. It is therefore suggested that heat treatment at this site was exercised along non-economic principles by people who were not very keen on improving technological efficiency, even when they could have easily done so.
