Title: Method of slip casting powdery material, using a water resistant mold with self-water absorbent ability

Abstract: A method of slip casting using a casting mold provided with a water-absorbent layer that has a self-water-absorbent ability, substantially has a water resistance, and is controlled in the saturated water content thereof, the slip casting being conducted by employing mainly a capillary sucking force as the driving force of the water-absorbent layer of cast formation. An open-cell porous body usable as the water-absorbent layer is produced by agitating a mixture comprising a compound having at least one epoxy ring in its molecule, a curing agent which cures the epoxy compound by reaction, a filler developing for a self-water-absorbent ability and a mold release property, and water to prepare an O/W emulsion slurry and curing the slurry, as such in a hydrous state.
