| 摘要 | PURPOSE: To prepare artificial stone having various colors and various patterns by prepg. colored frit from molten raw material compsn. comprising devitrifying material, coloring material, and glass, and sintering the colored frit. CONSTITUTION: Each devitrifying material component, coloring material component, and glass component is mixed with each other in the powdery state uniformly, and the mixture is melted completely in a heating furnace at ca. 1,300W1,500°C. Then, the molten body is quenched under supercooling condition causing no crystallization of the devitrifying material such as by flowing down in water stream. The cooled mass is crushed regulating the particle size to ca. 0.5W5.0mm particle size. The colored frit prepd. by the above described method is packed in a refractory shell plate in accordance with a specified design, and molded. After heating the molded body charged to a heating furnace to room temp. Wca. 400°C at 150W200°C/hr, it is further heated to ca. 600°C at 50W80°C/hr. Then, the heated product is held at near the softening temp. of the compound material for ca. 1W2hr, it is allowed to cool by standing to prepare the sintered body of the product.
