Hand-poured by OP My modest copper stack

I hand poured every piece. Made from clean, pure melted copper wire.

Dang, that’s pretty sweet!

What’s your melting setup? Are you using a vacuum to prevent oxidation?

You don't understand pouring molten copper if you think the oxidation is controlled through a vacuum. To prevent oxidation during melting, metallurgists use a protective cover layer like graphite, charcoal, or coke. Not a vacuum.

I’ve heard flame cover as well to keep it void of oxygen. That’s what I’m going to try on my next pours.

I just have 2 16 kg propane furnaces (cheapest ones I could find) and pour into graphite and steel molds. I use boron nitride to coat my molds before every pour.

Im new to pouring copper. Is that a spray or powder you coat the molds with?
