To provide the method of manufacturing an inorganic plate, by which the highly durable inorganic plate can be obtained.
In order to obtain this inorganic plate, a surface layer material is prepared by mixing a cement, pulps and water. The surface layer material is supplied to the surface of a base material mainly made of the cement. The method of manufacturing the inorganic plate is to form a surface layer made of the surface layer material through pressing. Water, which weighs 2.5-3.0 times that of the pulps is mixed so as to prepare the surface layer material. Since the surface layer material becomes hard to contain air, the base material and the surface layer can be brought into close contact with each other through pressing. Further, no lowering of the scattering state of the solid content of the surface layer material can be developed.
