Abstract: In a crystallized glass article consisting of crystallized glass masses fusion bonded together and having a principal surface, said principal surface having a surface pattern determined by said masses in a surface layer including said principal surface, said small crystallized glass masses in said surface layer are mainly of flaky crystallized glass pieces, each being a relatively large flattened piece, said flaky pieces overlapping one another at random to make said principal surface rough, said crystallized glass masses in another layer adjacent to and fused to said surface layer being considerably smaller than said flaky pieces. The article is produced by preparing flaky pieces and the smaller masses both of a SiO.sub.2 --Al.sub.2 O.sub.

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.
