It was shown that in order to obtain glazed ceramic material with heightened heat resistance the CLTE of the ceramic material must not exceed the CLTE of the glaze by more than 1.50 – 1.55%. It was found that separation into three or four regions occurs in silica-enriched glaze as a result of segregation of glass. The segregation structure appreciably decreases at 700 and 950°C. The temperature interval of segregation is a function of the conditions of heat-treatment of the glaze.
