NOVELTY - A human-tactile rock plate comprises a blank layer and a glaze layer sintered at 1280-1310 degrees C. The glaze layer comprises 250-500 g/m2 glaze comprising 25-35 pts. wt. mullite, 13-18 pts. wt. dolomite, 10-15 pts. wt. clinker, 8-13 pts. wt. quartz powder, 6-10 pts. wt. modified sepiolite powder, 5-10 pts. wt. modified vermiculite powder, 4-8 pts. wt. alumina, 2-6 pts. wt. expanded perlite, 2-5 pts. wt. calcium silicate, 2-4 pts. wt. calcium oxide, 1-3 pts. wt. calcium phosphate, 0.5-2 pts. wt. borax, and 0.2-0.8 pt. wt. boron trioxide. USE - Human-tactile rock plate. ADVANTAGE - The rock plate includes a glazed surface which is smooth, delicate, and flat, will not feel cold to touch, and is excellent and comfortable for human-touch. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the rock plate.
