Title:
FORMATION OF COLORED GLASS OF INORGANIC MATERIAL SURFACE BY IRRADIATION OF LASER AND SUBSTRATE FOR DECORATIVE MATERIAL
Document Type and Number:
Japanese Patent JP3813195
Kind Code:
B2
Abstract:
PURPOSE: To stably form a pink, a red or a brown colored glass layer which cannot be colored to an essential one according to a conventional method in the method for forming the colored glass layer on the surface of an inorganic substrate with an infrared laser.
