Abstract

PURPOSE:To form a glaze layer rich in luster by glazing a substrate with a lustrous glare containing an Nb compound and, as necessary, an alkali metallic compound and burning the glazed substrate. CONSTITUTION:Prescribed amounts of an Nb compound and, as necessary, an alkali metallic compound are blended with a basic glaze raw material (e.g. feldspar, quartzite, Gairome-clay, lime or alumina) and wet pulverized to prepare the objective lustrous glaze having a composition of 1-3 pts.wt. Li2O, 8-12 pts.wt. Na2O, 3-7 pts.wt. K2O, <1 pt.wt. Cab, <1 pt.wt. Fe2O3, 15-25 pts.wt. Al2O3, 55-65 pts.wt. SiO2 and 5-40 pts.wt. Nb3O5. The resultant glaze is directly applied to a substrate such as a tile or as a printing material is wholly or partially applied to a surface glazed with other glazes, dried and burned at 1100-1250 deg.C to afford a product having a glaze layer rich in lustrousness.
