Abstract
A crystallized glass article having a surface pattern like granite, marble or other natural stones with a line pattern of a desired color or colors, which is formed by fusion bonding small masses of a crystallizable glass material mixed with inorganic pigment powder at a heat-treating temperature higher than the softening point. The surface pattern comprises crystallized glass areas defined by the small masses in the surface layer of the article and the colored line pattern defined by the pigment dispersed in the interfaces between adjacent ones of the small masses in the surface layer.
