Abstract: PROBLEM TO BE SOLVED: To attain a strength surpassing the contraction stress at the time of drying and burning by making the wall thickness of a base of the peripheral part of an opening part provide in a drain casting forming part of a sanitary ceramic larger than that of the other portion. SOLUTION: A plaster mold is used in which the casting of a water supply port 3 of a forming plaster mold 7 and a water supply port forming part 8 corresponding to the peripheral part thereof, is formed at the speed (a square of casting wall thickness/casting time) substantially twice as much as that of the other portion. Drain casting forming is performed to make the wall thickness of base of the water supply port forming part 8 and the peripheral part corresponding thereto larger than the base thickness of the other portion. After such slip casting forming, the base of the water supply port corresponding part 3b is cut off by a jig 15 to form a water supply port 3.  As a result, the effect produced by increase in the base thickness of the water supply port 3 periphery completely prevents breakage and deformation at the time of drying and baking after forming, and cracks in construction or in use.
