I got a new crucible, but it's not ready to use just yet. First, i have to temper it! It's basically all the fun of metal casting, but without melting any metal. Doesn't sound fun? Well, you know what else doesn't sound fun? Having a crucible break full of molten metal because you didn't temper it, spilling it all over and burning you. Yeah. Think about that for a moment. Tempering doesn't seem like a bad idea anymore, does it?

To do this, I used hardwood lump charcoal and the improved mini metal foundry I built in an earlier video. The crucible is a #6 I think.

Anyways, i've gotten some questions about getting into metal casting, and tempering a crucible doesn't seem to be mentioned too often. I want to change that, because it's important.
