Methods of studying the raw material base of the pottery industry

The urgency of the issue is associated with the lack of a methodology for studying and identifying raw materials used for the production of non-glazed ceramics in Bolgar. The article considers the changes in the mineralogical and chemical composition of non-glazed ceramics in the process of its production. The leading method for solving this issue is the interdisciplinary approach with the use of technological experiments and physical and chemical research techniques. As a result, changes in the petrographic and elemental composition caused by various impurities of organic, mineral and organomineral origin were investigated. The materials of the article represent the first observations of the transformations taking place in ceramic dough in the process of technological manipulation.peer-reviewe
