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.engAttribution-NonCommercial-NoDerivatives 4.0 Międzynarodowehttp://creativecommons.org/licenses/by-nc-nd/4.0/PodkarpackieRzeszówsemi-maiolicaglazed potterySEM/EDSarticle10.15584/anarres.2019.14.9
