Interdisciplinary approach is becoming more and more essential in tackling different scientific problems in modern research practice. The paper describes an attempt to apply precise geochemical analysis techniques to the study of medieval wheel-thrown pottery unearthed during the excavations in North-Western Priladozhje. Mass-spectrometric (ICP-MS) analysis of ceramic shards’ clay from 48 pottery-ware samples and four specimens of clay from deposits in Southern Karelia and the Leningrad region was carried out to determine the possible provenance of the pottery. According to the chemical composition, the samples form three groups of vessels made of clay obtained from three different sources: local pottery made of red-burning clay, white-burning clay ceramics and imported ware. The results proved geochemical research is an effective method with good potential for further development in archaeological ceramics studies.
