Opacified Glazes Produced by High-Temperature Firing for Sanitary Ceramicware

The possibility of producing glaze coatings for sanitary ceramicware without using toxic compounds, such as barium carbonate and zinc white, is discussed. The regularities of variations in the physicochemical properties of glazes (luster, whiteness, microhardness, TCLE) depending on their chemical composition are identified in correlation with their structural specifics and phase composition.
