I recently upgraded my foundry to a propane jet burner and had a small accident during its second use...

Step 1: Turn on Burner and Place the Crucible in Immediately

Step 2: Wait Until the Crucible Explodes.

If you use a graphite or ceramic crucible, make sure to heat it up gradually and slowly. Or just use a metal crucible like I do now. Please vote for me in the epic fails contest! Thank you!

Forgot crucible outside for a while and moisture got into the graphite. When firing it up a month later looking dry, a terrifying bang. Part of the wall was split in half and shot away.

Evidently aluminium dissolves Iron - making a "solder"

I haven't had that problem
