Archaeometric investigation of the Late Chalcolithic-Early Bronze Age I and the 1st-2nd millennium BCE potteries from Kuriki-Turkey

摘要

In this study, potsherds belonging to the Late Chalcolithic-Early Bronze Age I and the second half of the 2nd millennium BCE-beginning of the 1st millennium BCE from Kuriki (Turkey) were investigated. Energy dispersive Xray fluorescence and X-ray diffraction were performed for chemical and mineral/phase analysis, respectively. Micro-Raman spectroscopy, optical microscopy and thermal gravimetric-differential thermal analysis were used as complementary techniques. Scanning electron microscopy and energy dispersive X-ray spectrometry were also performed for micro structural and micro chemical characterization. Results showed that mainly illitic and occasionally smectitic type of clays were used. Andesite, basalt, granite and limestone were found as the main sources of the minerals identified in the samples. Considering the decomposition and formation of the minerals, the results showed that potsherds were exposed to firing temperatures changing between 750 degrees C-950 degrees C. SEM images showed that the potsherds have a quite poor vitrification degree and heterogeneous grain distribution suggesting a simple firing technique. The results of this study suggested that despite a long time vacancy from the Late Chalcolithic-Early Bronze Age I to the second half of the 2nd millennium BCE, the ceramic production technology was presumably not changed drastically in Kuriki.
