Stone production public Left-Bank Ukraine in the final stage of Late Bronze Age

The article deals with the stone processing by the population of the final stage of the late Bronze Age of the Left-bank Ukraine on the materials of boguslavsko-belozerskaya culture (BBC) of the second half of the 13th –10th centuries BC. There are three stages in the development of this culture: the proto-BB stage (the second half of the 13th century BC), the BB1 stage (the 12th –11th centuries BC), the BB2 stage (the 10th century BC). Systematization of the materials shows that different kinds of stone goods which did not require much work input, special instruments and raw materials were being produced by boguslavsko-belozersky tribes in every settlement. However, professional training was necessary for manufacturing many tools when processing quartzite, granite, diorite, diabase and other kinds of hard stone. Morphological uniformity of pestle-sceptres, mortars, cylindrical grinders, smoothing irons presented in the artefacts of BBC and other cultures of the late Bronze Age of the Eastern Europe may be explained by the existence of the specialized manufacturing centers. It is also concerned the processing of silicon. Existence of the specialized silicon processing centers of the final stage of the late Bronze Age on the territory of the Left-bank Ukraine is proved by the materials of the settlements Dibrova, Glubokoie Ozero-2 of the Seversky Donets situated near siliceous cretaceous screes. It gives evidence of the revival of silicon processing at the BB1 stage. Further development of silicon tool manufacturing by the tribes of BBC was at the BB2 stage. It was most significantly revealed in silicon sickle spreading. Probably a short-term revival of the stone industry in the 12th –10th centuries BC on the territory of the Left-bank Ukraine was caused by the inevitable shortage of raw materials during the transition period from bronze metallurgy to iron metallurgy.
