Are you certain of that? I received regular orders from Colt, in West Hartford for these "crucible". In the case of Colt, they were a 5x5x10" box, cast in a martensitic alloy (called CA6-NM, for those that care) I have been in the heat treating department at Colts many times, and, at least in their case, the boxes aren't unclamped until back to room temperature.
