Preliminary results of the technical and technological analysis of the Neolithic - Bronze ceramics from the Khedugin Ruchey site (the Northern Angara)

Data of the technical and technological analysis of ceramics are crucial for a resolution of the problem of population migrations in the northern Angara region during the Neolithic - Bronze Age. Raw materials and pottery paste of 81 vessels from the Hedugin Ruchei site were studied through the historical-cultural approach. The ceramics was mostly made of ferruginous clay with a considerable sand admixture. Eight recipes of pottery paste were identified. The local compositions represent clay with gruss and without artificially introduced mineral admixtures. Mixture of skills in ceramic manufacturing is noted. The noted considerable number of recipes and several cultural traditions suggest that there were several distinct groups of the potters. It can indicate population migrations and a complex population structure during this period, and their chronological distinctions.
