The paper presents the results of the technical and technological analysis of Andronovo ceramics obtained during the rescue excavations in 2020 at the multi-time settlement of Firsovo-15. The composition of the raw materials and molding masses of 18 samples was studied. It was found that most of the vessels were made of medium-hard plastic clays. In total, two recipes for composing molding masses have been identifi ed: clay + chamotte + organic solution, clay + chamotte + organics. Comparison of the data obtained with the result of earlier studies of the materials of the monument allows us to speak of a high degree of uniformity of the Andronovo ceramic complex of the Firsovo-15 settlement. A comparative analysis of the results with the available information on the technology of making ceramics of other Andronovo settlements of Altai demonstrates some originality of the studied complex. It consists in a small variety of recorded recipes, as well as in the presence of the only one type of mineral impurity in the studied sample. The results obtained indicate that the population who left this site had stable traditions in the selection of raw materials and the composition of molding masses, as well as its cultural unity.
