I have zero foundry experience. I want to melt a few pounds of Copper and
cast it into backup plates for welding. What should I make the crucible
and
moulds out of? OR, is it possible to buy a crucible somewhere?
Thanks.

[Nobody casts pure copper. It takes a lot of heat, and oxidizes badly. If
you want back-up plates for welding, why not just get some copper plate and
cut it up?]
