A multidisciplinary analysis of ceramics from six sites of the Surgut variant of the Kulaika culture at Barsova Gora was made. Technology was assessed using traceological, petrographic, and X-ray phase analyses. At all the sites, the potters used ferruginous clays tempered with grus, grog, sand, and organic material. Fragments in the clay were either rounded, as in sand, or coarse, as in grus. The sand was mainly represented by feldspar and quartz, suggesting that this type of raw material was extracted from nearby non-metallic mineral deposits. The grus consisted of fragments of basaltoids, amphiboles, and pyroxenes, evidencing that it came from igneous common rocks associated with the Surgut volcanic fi eld and spread over a large area. Rocks were probably mined near settlements, perhaps on the floodplain of the Ob. Grog in all the samples was similar to the basic clay in terms of its composition. Three groups of sites were identified, differing in the composition of the clay of which the ceramics were made. This may indicate the presence of several groups within the Iron Age Kulaika population, utilizing various sources of clay.
