Effects of ZrO<sub>2</sub> on Zinc Crystalline Glaze

Zinc Crystal Glaze has its limits in practical use of commercial glaze due to the sensitive firing schedule. In order to overcome these limits, and to improve the practical usage, this study is aimed to develop a stable zinc crystalline glaze. This study altered the quantity of nuclear formation of zinc crystal glaze in order to control the willemite (Zn 2 SiO 4 ) formation in the glaze. The addition of ZrO 2 to zinc crystal glaze influences the quantity of nuclear formation and its preservation; thus ZrO 2 was used to control the optimal firing temperature and the size of the crystal formation in the glaze to find a zinc crystal glaze capable of withstanding various ranges of temperatures.
