The paper presents the study of stress relations of ceramic body - glaze systems of model and real, both historical and contemporary ceramics. The systems were characterized in terms of chemical composition, linear thermal coefficients and degradation effects. The results show that calculation of stress relations between ceramic body and glaze is affected predominantly by the difference in values of thermal expansion coefficients. Calculated results provide relevant information about the accordance of the glaze - ceramic body and for the characterization of surface defects.
