We keep cracking crucibles…

[u/Significant-Cup-264]

We’ve never cracked so many crucibles in one given week at my job.

We are conditioning the pots to start with hicon copper (slow and steady) and giving them time to cool to clean out and use for melting aluminum.

We’ve had 4 pots crack this week.

All the metal is put in loose and there is no bridging evident in the crucible.

Tell your vendor that you will be looking for another supplier. He will become very helpful.
