A self adjusting consumable hot top is formed of a pair of bendable shape adjusting sections of a combustible consumable material capable of being wedged into opposed relation in an ingot mold so that the hot top conforms with the shape of the cavity in the ingot mold and when ignited by molten metal poured therein adds heat to the molten metal to maintain a pool of molten metal for filling pipes and cracks in the cooling ingot.
