What to use for a small crucible?
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?
Thanks,

PS. The two []'s and four ='s are just one brick.

dont take to much from this cause i to am looking for a crucible. but that will in no way wotk. if the mud dosent wall apart it will be burnt through from the liquid metal. i know this pretty well from old experiments if had when extreme heat meets dirt. was kinda fun =)
