Abstract: This paper investigated the effects of the content of alkaline earth metals on the quality of ground and surface glazes of the interior wall tiles through a series of experiments. Analysis of the glaze appearance, initial melting point and microstructure suggests that the glaze is the best in quality when the content of alkaline earth metals in the surface glaze is similar or equal to that of the ground glaze. This study is expected to provide some guidance for the optimization of ceramic glaze recipes, the reduction of glaze defects and the production of enterprises.
Key words: alkaline earth metal; glaze quality; practical production
