Microwave Melting of Metals

A "foundry in every kitchen". Special crucible construction techniques to make microwave smelting and casting workable. An all in one crucible and mold is made, the metal is melted in a very slightly modified (masking tape over vent holes) microwave, about 17 minutes for a third of a kilo of silver, then the crucible/mold is inverted to make the casting. Clever and appealing.
