Patent ID: 7913516

Claim:
A method of producing crystallized glass articles having patterns, comprising the steps of: providing a first crystalline glass layer comprising at least one first crystalline glass plate; providing a second crystalline glass layer on or below the first crystalline glass layer, the second crystalline glass layer comprising a plurality of small crystalline glass masses and/or at least one second crystalline glass plate; and performing a heat treatment to fusion-bond the first crystalline glass layer and the second crystalline glass layer into a whole and to precipitate crystals therein to form the crystallized glass article having marble-like patterns and a specific pattern different from the marble-like patterns, 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, the marble-like patterns and the specific pattern are formed by softening and/or fusion-bonding 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.
