Sand casting, lost-wax (investment) casting and die casting, from backyard furnaces to industrial foundries. Molten metal is dangerous: work outdoors on dry sand, never let molten metal touch water or damp tools (steam explosions), wear leather boots, gloves and a face shield, and avoid lead and zinc fumes. OSHA's lead and silica pages cover the main foundry health hazards. Suppliers below are commercial.
