  • Patent number: 6527628
    Abstract: The present invention provides a method for producing a frosted glass product, where a sand blast processing using a powder class abrasive and a brush polishing treatment are performed and thereby appearance and touch feeling equal to those of a product worked by the chemical frost processing can be attained. In particular, the present invention provides a method for producing a frosted glass product, which is safe in the work and at the same time, mild to the environment. The invention is a method for producing a frosted glass product, which is a method for obtaining a glass product having a delustered surface such that the surface roughness Ra of the glass is from 0.4 to 1.2 &mgr;m, the method comprising a step of sand-blasting a glass surface using an abrasive having a grain size of less than #220, and a step of brush-polishing the sand-blasted surface.
