The subject of this paper is an analysis of the residues of black tarry substances found on the exterior surface of one, fully reconstructed vessel, as well as the interior of two belly parts of the other vessels coming from the site 1 at Chwalim (Lubuskie voivodeship), identified with Para-Neolithic Niemen culture. The parts of the mentioned vessels were used as samples for the physicochemical analyses. These samples were analyzed with a series of methods: the IR spectrophotometry, EPR, microscopic observations (polarizing microscope PZO and Philips SEM electron microscope), a melting point measurements (PHMK 05 apparatus) and solubility test.
