ABSTRACT:
A crystalline glass with a characteristic of precipitating crystals from the surface of the crystalline glass to the interior thereof when it is being heated at a temperature higher than the softening point is used in the invention. A plurality of small crystalline glass masses12are accumulated and leveled in a fireproof mold coated with a mold release agent, and two crystalline glass plates14A and14B cut in an S shape are placed on the accumulated surface of the small crystalline glass masses12with the cut faces tightly bonded. A heat treatment is then performed to obtain a crystallized glass article having patterns. The crystalline glass plate can be cut into any shape to tightly bond the cut faces, and therefore the obtained crystallized glass articles have different patterns like natural-marble-like patterns, human figure patterns, animal patterns, etc. The invention also discloses a method of producing crystallized articles having patterns.
