This article discusses tenth–sixteenth-century pottery kilns in the Carpathian Basin in the territory of medieval Hungary. Kilns are classified on the basis of their structure, building technique and firing technology and these characteristics are examined using archaeological evidence, ethnographical sources and also technological and pyrotechnical analysis. The archaeological and stratigraphical features and some methodological problems of medieval pottery kiln study are also discussed and a topographical analysis of the pottery kilns in relation to the workshops and settlements on the basis of archaeological and historical evidence is presented. The history of the development, origin and distribution of the types of medieval pottery kilns in the Carpathian Basin is also presented. There is a brief discussion of the contribution that pottery kiln studies can make to the understanding of workshop organization.
