This website was set up to present the results of an interdisciplinary project entitled Sources and Distribution of Selected High and Late Medieval Pottery Products (GA 17-13967S), exploring the production centres of selected pottery items in the high and late Middle Ages by means of analytical methods, as well as a closer definition of mutual contacts in the production sphere. The key commodities are stove tiles with which, due to their relief decoration, macroscopically identical specimens have been identified at different locations. The amount of information about the functioning of medieval pottery workshops allows us to presume that the sources of material of the examined specimens were identical with those of small sculptures, aquamaniles and floor tiles. The assessment of the scientific analyses of the samples of these pottery products with a more profound aesthetic effect, executed within the project, will provide groundwork for the definition of material groups, with the possible locating of the deposits of clay used in their manufacture and, together with conclusions derived from use-wear analyses, will indicate the directions of migration, the evidence of which will be sought in archive sources. The results will be presented in an electronic publication related to this website.
