This paper presents the results of research on aluminum silicate sanitary glazes in the SiO₂-Al₂O₃-CaO-Na₂O system with different SiO₂/Al₂O₃ molar ratio. XRD, SEM-EDS and FITR measurement indicated that SiO₂/Al₂O₃ molar ratio has a significant impact on the phase composition of the obtained glazes. Glass-ceramic glazes were obtained that consisted of both the glass phase and pseudowollastonite (Ca₃[SiO₃]₃) or anorthite (Ca[Al₂Si₂O₈]) crystals. Subsequently, the influence of phase composition on surface quality (roughness) was examined for the obtained samples. On the basis of the conducted examination of glaze surface roughness was observed that glazes of extreme SiO₂/Al₂O₃ molar ratio are characterized with greatest surface roughness when compared to other glazes.
