ABSTRACT:
A crystallized glass article with a colored surface pattern, which comprises a crystallized glass substrate having a surface and small glass masses having a color different from the substrate and dispersed and fusion-bonded in the surface to form the colored surface pattern. The crystallized glass article is produced by depositing and dispersing small glass masses with a color on a surface of a substrate of a crystallizable glass with a different color which can precipitate crystals therein with softening and deforming by heat-treating at a heat treating temperature higher than the softening point of the crystallizable glass, then heating the substrate together with the small glass masses at the heat treating temperature.
