▎ 摘  要

NOVELTY - A rock plate comprises a blank layer and a glazed surface layer, from bottom to top. The glazed surface layer is formed by spraying 300-600 g/m2 rock plate glaze, and sintering at 1240-1260 degrees C. The glaze is made by mixing 20-30 pts. wt. potassium feldspar, 12-20 pts. wt. frit, 10-16 pts. wt. quartz powder, 10-15 pts. wt. talc, 6-10 pts. wt. bentonite, 4-8 pts. wt. barium oxide, 4-8 pts. wt. dolomite, 4-8 pts. wt. modified hydroxyapatite, 2-5 pts. wt. modified magnesium oxide, 1-3 pts. wt. magnesium borate whiskers, 1-2 pts. wt. sodium metaaluminate, 1-2 pts. wt. calcium phosphate and 0.5-1.5 pt. wt. borax. USE - Rock plate. ADVANTAGE - The flat rock plate is prepared with baby skin-like feel and smooth surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the rock plate.
