Abstract
A slip casting mold includes a water absorption layer having self water absorption capability and substantial water resistance. With the water saturation percentage of the water absorption layer being controlled, a slurry layer is deposited in the slip casting mold mainly under capillary attractive forces of the slip casting mold. The water absorption layer comprises an open porous body which is manufactured by stirring a mixture of an epoxy compound having at least one epoxy ring in one molecule, a hardener for reacting with the epoxy compound to harden the epoxy compound, a filler for developing self water absorption capability and mold releasability, and water into an O/W-type emulsion slurry, and casting the emulsion slurry into a mold impermeable to water, hardening the emulsion slurry in the mold while containing water.
