Artificial stone

Abstract

The following artificial stone having a deep color tone and a glaze and having a luminousness is provided at low costs. An artificial mixture in which a fine powder component of an inorganic material having a size of from 5 to 70 mesh is used, the sum of this fine powder component and a finely divided component of an inorganic material of 100 mesh-under is 89% by weight or more of the product and a resin component is 11% or less is struck and integrated into a cured slab which has been cured.
