Abstract:
1. A crystallized glass article having patterns, comprising: (A) a first crystallized glass layer, which is formed by at least one first crystalline glass plate, wherein the first crystalline glass plate is of a crystalline glass material having a characteristic of precipitating crystals from the surface of the crystalline glass material to the interior thereof when being heated at a temperature higher than the softening point, marble-like patterns and a specific pattern different from the marble-like patterns observed on the crystallized glass article are formed by heating the first crystalline glass plate at a temperature higher than the softening point to precipitate crystals therein, and the specific pattern varies with the shape and/or the combination of the at least one first crystalline glass plate, wherein the first crystallized glass layer is formed of a crystallized glass containing precipitated β-wollastonite (β-CaO.SiO (B) a second crystallized glass layer stacked on or below the first crystallized layer, the second crystallized glass layer being formed by softening and/or fusion bonding a plurality of small crystalline glass masses and/or at least one second crystalline glass plate through a heat treatment to precipitate crystals therein.
