ABSTRACT:
A process for producing stained crystallized glass and its articles which is characterized in meeting production of various crystallized glass articles in small quantity. By this process, crystallized glass is obtained with patterns and colors alike to that of granites, marble, and other natural stones. The process of heat-treatment to a prepared batch compounded of crystallizable glass granules, color powder and water at a temperature higher than the softening point thereof results in fusion bonding of the glass granules. The color powder is compounded by inorganic pigment, suspension stabilizing agent, agglomerant, deflocculant agent, and crystallizable glass powder. The surface pattern is formed by grain boundary part of crystallizable glass granules, and part of the inorganic pigment in the color powder moving with the crystallizable glass powder.
