Hi, /diy/. I kind of need a solution, but its still related to diy topic/subject. Basically I'm going to make one of those little furnaces to melt aluminum and copper. I basically have everything already, only thing I dont have is a crucible.

Basically I cant find a steel fire extinguisher thats 3" in diameter. I have a crucible in the mail, but its gonna be a few weeks.

One of my friends said you could use plaster for a mold, but it would be harder to transfer heat but it would still work.
I kind of need help finding out what to use for temporary crucibles that are easily obtainable.

TLDR; I need an easy cheap makeshift crucible

I see this as DIY still and would like to see if you all have any solutions to offer, thanks in advance

Stoneware is good, but make sure it *IS* stoneware. Regular glazed ceramic mugs will shatter in a furnace, causing you to lose you melt.
