The article introduces into scientific discourse the materials of the burial 15 of the Trikolsky burial ground studied in 1978 by V.A. Ivanov. This burial featured finds unique for the entire Pyany Bor culture – a glass bowl and a cassolette. The burial also contained beads made of single-color and multi-colored glass and glass with a metal inlay, pendants made of adult moose incisors, bronze plaques, openwork overlays, temple pendants, etc. The authors concluded that the unique items came to the Pyany Bor population as a result of contacts with Sarmatian nomads in the 1st century AD. In addition, the study presents data on the manufacturing material of certain items obtained using natural scientific methods. It was determined that the cassolette was made of a sedimentary rock – argillite. Metal items, except a leaf-shaped pendant made of precious metal, are made of tin bronze. A “gum” sample discovered next to a glass bowl contains matter of vegetable origin. Its components are betulinic and tricyclic acids contained in birch bark and conifer resin (oleoresin), respectively.
