If moisture is on your crucible when you try to heat it—even if it’s not visible to the naked eye—it will flash boil. This will cause the item to crack or explode, which is very dangerous. You don’t know what dampness the crucible has been exposed to, so you must temper it to eliminate any moisture.
How long do you temper a crucible?
Where possible the crucible should be pre-heated empty. The power input rate should initially be limited until the crucible becomes bright red over its entire surface. The time taken to pre-heat will depend on the size of the crucible, but is normally in the range 20-40 minutes.
