In the archaeological context, substances with a black color have been extensively used in many ancient communities, in the form of items and layers, with the use of biogenic and mineral substances, and requiring a separate methodological approach. Each of them behaves differently in technological and postdepositional processes. The potential degree of the complexity of intentionally applied layers (e.g. paints or cosmetics) and the overlap of secondary substances and crusts, increases difficulties in obtaining unambiguous results and their interpretation. Graphite plays an important role among them. Several areas of the current use of graphite are, or at least could be, commonly shared in the present and in the past, and thus their analysis could be inspiring for archaeology and archaeometry. Graphite fingerprint and potential fingerprints are discussed in terms of their variability. The problem of graphitization as a potential source of misleading interpretation is discussed.

Steadily growing collection of modern ceramics of the present Podkarpackie Voivodeship, has not yet been fully documented. Historical research demonstrates that Rzeszów, located on the communication route with Russia, occupied a very important position in trade relations with the East and West. The archaeometric study was performed on two fragments of semi-majolica plates and six fragments of glazed jugs, pots and tripod vessels. Vessels were made of fine-grained paste of smectite/illite, kaolinite/illite and kaolinite/illite/smectite clay. The richness of colours and shades is surprising. In the case of semi-majolica, the underglaze paintings were made with the use of frit pigments, while the overglaze ornament was made with the use of Pb-P-Ca-Si paste. ‘Slip-painting’ technique was also used. Glazes were coloured with iron, copper and cobalt compounds of various combinations and concentrations which provided different shades. In the case of semi-maiolica quartz-argillaceous primer with a potassium-bearing substance was applied, surfaces under glazes were covered with flux-bearing substances
