Claim 1
Independent Claim
80 words
A PROCESS FOR THE PRODUCTION OF FUSED GRANITE SHAPES COMPRISING FORMING PULVERIZED GRANITE PARTICLES INTO "GREEN" SHAPES WHICH ARE AT LEAST 93% OF THE DENSITY OF THE SOLID NATURAL GRANITE FROM WHICH SAID PULVERIZED GRANITE PARTICLES ARE OBTAINED AND FIRING SUCH "GREEN" SHAPES AT A TEMPERATURE IN THE RANGE OF 1150*-1300*C. FOR A SUFFICIENT TIME TO CAUSE SURFACE FUSION OF THE LOWER MELTING POINT CONSTITUENTS OF THE GRANITE PARTICLES THROUGHOUT THE MASS SO AS TO CAUSE COHERENCE OF THE PARTICLES.
