ABSTRACT:
Metal castings are prepared using rigid closed molds by submerging the mold in a bath of lower temperature molten metal, with removal of the mold from the bath being handled to hold the metal inside the mold, but to allow the excess metal to run off the exterior of the mold without metal freezing thereto which could cause damage or locking-in of the mold.
