The paper reviews current and future demand for raw materials for "gres porcellanato" tiles production in Poland. Among the main raw materials necessary for their production, shortages of domestic supply of white- and light-firing ball clays occur. The paper presents domestic sources of white- and light-firing clays, as well as the quality of these raw materials. In detail, the analysis of foreign sources of white-firing ball clays for the Polish ceramic industry, especially for "gres Porcellanato" tiles production, has been carried out. Ukrainian, German and Czech producers of ball clays are presented, together with quality characteristics of raw materials delivered by them. Finally, perspectives of future supplies of white- and light-firing ball clays to Polish "gres porcellanato" tiles industry (both domestic and imported) are discussed.
