Light-transmitting decorative glass, decorative glass, and method and apparatus for manufacturing decorative glass

摘要

Provided are decorative glass and light-transmitting decorative glass products which are outstandingly decorative by processing a surface of a translucent glass plate, typically used as building materials or for other uses, without impairing the strength of the glass itself. The surface of the translucent glass plate 1, which is 4 to 25 mm in thickness, is impressed to form a plurality of radial cracks 7 each having a diameter of 0.01 to 3.0 mm, so that dots of the cracks 7 form an arbitrary character or pattern to thereby manufacture the decorative glass product. The light-transmitting decorative glass product includes the decorative glass, and a light source which is disposed so as to allow a highly directive irradiating beam to be incident upon any one of the four sides of the translucent glass plate 1 and enter the translucent glass plate.
