Cast Iron Crucible and Cracker

Iron melts at 2800 °F. Pewter melts at 450 °F. If Momma Donna tossed her cracker into that crucible it would explode like an ice cube in hot tea. Unlike the ice cube, the cracker would vanish in a puff of pewter steam. This iron casting foundry is in Tennessee and still in operation.
