A possible source of raw material for ceramics from the area of the towns Yambol and Elhovo – preliminary results

The application of geological methods of investigation to archeological objects gives the necessary information about the source of materials (rocks, clays, etc.) for preparation of different tools during the Prehistoric time. Using XRF analyses of clays from natural outcrops along the valley of the Tundzha River and of ceramic vessels from the area of the towns of Yambol and Elhovo we found out that these vessels were prepared from clays from this region.
