Abstract
A crucible for exothermic welding includes a frame and two semi-cylindrical or rectangular refractory blocks which include abutting planes through a reaction chamber and a sprue hole. One block is mounted for movement with respect to the other from an aligned mating position forming the chamber and sprue hole to an offset position which movement loosens slag formed during the welding process, and greatly facilitates cleaning. Adjustable spring ball rollers maintain the parting plane pressure.
