P.S. One of the beauties of casting with aluminothermic reactions is there is no crucible used (or furnace)! You plug the sprue (entry) going to the mold cavity with a thin sheet of metal (that is melted once the molten metal reaches it), and put the chemical on top. The slag melts to the top and the metal drains out into the mold....
