Abstract
A ceramic mold made up of Al.sub.2 O.sub.3, a silicon oxide mixture, C.M.C., CaCO.sub.3, Fe.sub.2 O.sub.3 or CoO, and water through a forging process under temperature within 500.degree. C. to 1600.degree. C., having a net of permeation holes on the inside and a guide tube disposed on the outside for drawing water from said net of permeation holes out of the ceramic mold or driving air into said net of permeation holes.
