What to use for a small crucible? Answered
I want to make a small backyard aluminium foundry, but I don't know what to use as a crucible. I've seen soup cans, but it says they rust away, and ceramic shatters. I've also seen things like the bottom half of a propane/co2 canister, but I don't have thing like angle grinders to cut it open.
Also, how would I make the foundry? I was thinking of laying down fire bricks in a pattern like this:
(from top, looking down)
 O ===O < blower
with mud to fill in the cracks. Would this work?
PS. The two 's and four ='s are just one brick.
