The publication is focused on late medieval pottery products with higher aesthetical effect. The key group is represented by stove tiles, where the unifying elements of relief decoration helped to define series of motifs for stoves with specific iconographic concept, which were found in various locations. The same approach can be also used with small ceramic sculptures, aquamaniles and relief-decorated floor tiles, even though the achieved information value in these cases is much lower. Micropetrographic, XRF and other analyses helped to identify the production centres and the distribution model of these ceramic groups. 3D documentation enabled a detailed comparison of differences between individual reliefs and specific traces of manufacturing procedures. Individual chapters contain active links to the source database of analysed items and to 3D models of selected specimens from reference collections.

Příspěvek představuje výběr třinácti pozdně středověkých a raně novověkých zlomků a torz kam nových kachlů s otisky textilií na rubu čelní vyhřívací stěny ze sedmi brněnských lokalit, u nichž byl dle možností určen typ textilní vazby a byla provedena mikropetrografická analýza, která prokázala výrobu z místní keramické suroviny získávané z jednoho rozsáhlejšího těžebního areálu na terase řeky Svitavy. Použití textilie je spojeno s materiálem střední zrnitosti a ovlivněno individuálním zvládnutím procesu for mování čelní vyhřívací stěny. Klíčová slova: kamnové kachle-petroarcheologické analýzy-otisky textilu-středověk-raný novověk-Brno.

Archaeological research in the complex of the Brno chapter at Petrov yielded a series of greenglazed incised tiles from the ledge of a knight stove (angel the shield-bearer). The tiles were made in 1454-1457 by a royal workshop in Buda for King Ladislaus the Posthumous. The frequency of the finds of the remains of these stoves in Brno (different types from at least eleven locations) led to the exact determination of the provenance of the Petrov series, the main objective being to contribute to a deeper knowledge of the forms of transport of luxury tile stoves at the onset of the late Middle Ages. The tiles were subjected to micropetrographic analyses, which showed that local ceramic material rich in grog was used for their manufacture. In all probability, it came from the vicinity of Petrov. Analyses of the glazes by means of XRF and SEM-EDX revealed no traces of alkali components in the green glazing on the surface of the tiles, and confirmed that primarily PbO was used as a melting agent. The specific green tint was achieved by the addition of 2-3.5 % of CuO. The tiles were fired in chamber kilns at temperatures around 1000 °C.
