Abstract
The present invention provides transparent chips with natural metal-like texture by coating silica-containing transparent chips with colored material, such as a metal powder, in a transparent resin as a base resin. The present invention also provides artificial stone with natural metal-like texture and patterns by mixing the colored material coated transparent chips and inorganic filler with a matrix resin. The artificial stone of the present invention can be prepared by mixing about 4 to about 24 parts by weight of inorganic filler and about 0.1 to about 5.0 parts by weight of the colored material coated transparent chips, per about 1 part by weight of the matrix resin. The colored material coated transparent chips can have a specific gravity of about 2.0 to about 2.65, while the matrix resin can have a specific gravity of about 2.2 to about 2.8, and the specific gravity of the transparent chips can be equal to or lower than the specific gravity of the matrix resin in promote uniform distribution of the transparent chips in the matrix resin.
