Abstract 1. IN A METHOD FOR MANUFACTURING A HARD PROCELAIN ARTI CLE OF HIGH WHITE TRANSLUCENCY AND HIGH STRENGTH WHICH COMPRISES: FORMING A PLASTIC GREEN BODY, FIRING TO FORM A BISCUIT, GLAZING AND GLOST FIRING SAID BISCUIT, THE IMPROVEMENT WHICH COMPRISES FORMING SAID BISCUIT BY: A. PULVERIZING MGO OR AN MG COMPOUND AND SIO2 SO THAT MORE THAN 80% OF THE RESULTANT MIXTURE HAS A GRAIN SIZE OF UNDER 10U, THE RATIO OF MGO OR MG COMPOUND TO SIO2 BEING 40 PARTS BY WEIGHT, AS MGO, TO 60 PARTS BY WEIGHT SIO2, B. MIXING TGE MIXTURE OF STEP A WITH 2 TO 3% OF LIO2CO3, BACO3 OR PETALITE AS A MINERALIZER, C. FORMING A SINTERED MIXTURE OF PROTOENSTATITE, CLONOESTATITE, FORSTERITE AND SIO2 BY SINTERING THE MIXTURE OF STEP B AT 1240* TO 1350* C., D. MIXING (1) 10 TO 18 WT. PERCENT GAEROME CLAY (29 6 TO 12 WT. PERCENT KAOLIN (3) 0 TO 3 WT. PERCENT FELDSPAR (4) 8 TO 10 WT. PERCENT MURAKAMI CLAY (5) 0 TO 6 WT. PERCENT ALUMINA (6) 54 TO 67 WT. PERCENT OF THE SINTERED MIXTURE OF STEP C, E. FORMING A SLURRY WITH THE MIXTURE OF STEP D AND WATER AND MILLING SAID SLURRY TTO PULVERIZE SAID MIXTURE SO THAT MORE THAN 80% OF THE PARTICLEES THEREOF ARE UNDER 10U, F. FORMING A PLASTIC GREEN BODY AND DRYING SAID BODY TO REMOVE WATER THEREFROM, AND G. FIRING SAID BODY AT 900-1000* C. TO PRODUCE SAID BISCUIT.
