Do you think there might be a reason why commercially made crucibles are as expensive as they are? If it were possible to just make one out of clay I think more people would be doin it. My thoughts are- if you want to try, good luck. What are the accident and emergency facilities like at your local hospital?

What I would be more inclined to do would be to make a cupola and recast the cast into something you need.

Matt I know almost nothing about the subject but remember a similar exchange of views across the street several months back. If ever you are there it would be worth trawling the archives to see what was said.
