   The method of preventing the formation of shrinkage cavity within bottom cast ingots which consists introducing the metal into the mould through a dozzle and a plate having a plurality of inclined conduits, whereby the incoming metal is directed against the walls of the dozzle, this heating said walls to incandescence, then reversing the mould, said dozzle after the mould is reversed causing the metal in contact therewith to feed downwards into any shrinkage cavity within the ingot.

   When the metal has risen to within, say, 3 inches of the top of the mold, a “dozzle," which has been previously heated in one of the holes, is quickly dropped on top of the metal in the mold, and held in position whilst the few pounds of metal remaining in the crucible are poured through its center.
