Abstract
In casting metals for dental prosthetic use, superior dental castings free from shrinkage cavities can be obtained by delaying the cooling and solidification of molten metal in mold members such as a sprue, runner and gate and, if necessary, a molten metal reservoir into which the molten metal is poured. Such delay in cooling and solidification can be achieved either by forming the sprue and the like from a heat resisting ceramic tubular body or by further forming a heat insulating layer on the outer periphery of the tubular body.
