Abstract
Improvement of surface quality of glossy-opaque floor tile glazes by decreasing pinhole problem was the main purpose of this study. Glossy-opaque floor tile glaze was produced by mixing three different frit compositions. Effects of frit compositions on glaze surface properties were investigated by thermal analysis. Two hypotheses were improved and applied in terms of the analysis results. It was found that pinhole problems can be solved by optimizing softening point of glaze composition and glossy-opaque glaze with enhanced functional and aesthetic features can be obtained by homogenously distributed nano size crystals.
