Abstract
A pressure casting mold used to mold sanitary earthenware, including a porous layer composed mainly of resin material, a filler, a curing agent and water, the filler being formed of fibers and particulates of glass material, an average diameter of the fiber filler being 1 through 10 .mu.m, and an average length of the fibers being 20 through 100 .mu.m, and the diameter of the particulate filler being 10 through 50 .mu.m, thereby obtaining a porous layer which in use is hard to clog and is high in durability.
