    • PURPOSE:To produce an excellent decorative inorganic substrate without deteriorating materials of plate glass and board material, by fusing both with specific frit powder fusing the plate glass for forming a decorating surface to an inorganic substrate and integrating to produce an inorganic material having the glass plate decorative surface. CONSTITUTION:Window glass, colored glass, tempered glass, etc., forming a decorative surface is bonded to a board material, e.g. alumina porcelain board, cement formed board, calcium silicate board, tile body, inorganic expanded board, other inorganic heat-resistant building boards, etc., having / deg.C difference in thermal expansion coefficient from the above-mentioned board material to produce a decorative inorganic substrate. In the process, frit powder having an intermediate value of the thermal expansion coefficient between those of both plate and board materials and melting point >=50 deg.C lower than the glass material is placed between both plate and board materials in 0.005-0.20g/cm amount used and both materials are laminated and heated at a temperature below the deformation temperature of the glass plate material. The frit is fused to firmly bond the glass plate material to the inorganic board material without damaging by the difference in thermal expansion coefficient.
