Modern Semi-Majolica and Glazed Ceramics from Rzeszów – Research on the Findings from the Archaeological Sites on 3 Maja Street
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2019) Trąbska, Joanna; Kocańda, Paweł; Trybalska, Barbara
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.
Spongiolitowa forma odlewnicza ze stanowiska nr 20 w Przemyślu. Rezultaty badań

Site No. 20 in Przemyśl, is an important research point of the early medieval city. During field works, two parts of a casting mould for the production of axes were found at the bottom of the settlement layer. No traces of copper were observed on the discovered form, but there were visible signs of burnout outside. This form is affiliated to the Mierzanowice culture. Petrographic tests have been performed using polarizing and scanning microscopes as well as microapaleontological examinations. They allow the researchers to identify the mould material as spongiolite (spiculite), most likely coming from the vicinity of Przemyśl, where the outcrops of this rock are located. With high probability, it can be stated that this material comes from the upper part of the Lgota beds covering the aforementioned lithostratigraphic units. The type of raw material used meets the conditions for using it as a casting mould. The obtained data allow for conclusion about the local production of this form.
