Refractory insulating material is disposed between the bottom end of the hollow body and the bottom wall of the mold and between the sides of the hollow body and the sides of the mold, the hollow body being subsequently charged with a molten base metal. Prior to inserting the hollow body into the mold, the bottom end thereof is sealed closed by a bottom wall and a cover plate is placed on the top end of the hollow body.
