Features of the selection of raw materials for the production of ceramics by carriers of the Novosibirsk version of the Kulai culture
A technical and petrographic analysis of the ceramics of the novosibirsk version of the Kulay culture from the Kamenny Mys and Dubrovinsky Borok-3 sites has been carried out. It was found that the same type was used as a raw material at both sites — natural clays. It has been determined that, according to the mineral composition, different groups of clays are distinguished: three on Kamenny Mys, and two on Dubrovinsky Bork-3. The correlation between the groups of clays and the compositions of clay paste demonstrates that the difference is manifested not only in the skills of selecting clays by potters, but also in the skills of drawing up molding masses with different groups of clays. When comparing the clays from the two sites, it was determined that they differ significantly from each other in their mineral composition.
