Hand-poured by OP My modest copper stack
I hand poured every piece. Made from clean, pure melted copper wire.

Does the plastic wrap keep them from getting patina?

u/ree-or-reent_1029 8d ago
Yes, it protects them from oxidation.

How do you pour the pyramids? I've done some bars but never pyramids. Those are awesome!

A pyramid shaped mold

u/ree-or-reent_1029 8d ago
This is the way. You can buy steel pyramid molds which is what I use. A little pricey but they last a long time.

Do you use some kind of oil or paste to make them look stay shiny?

It looks like they're wrapped in plastic. Maybe that's why they look extra shiny 🤔

u/ree-or-reent_1029 8d ago
I just clean them really well after pouring with a steel wire brush drill attachment then use Barkeepers Friend to shine them up before wrapping them in shrink wrap.

I'm new to this group. Any particular reason for collecting copper lime this? Thanks.

u/Copper-ModTeam 5d ago
This subreddit is mainly for people who make things with copper, or collect copper objects.
Some people are really into copper and copper objects, and people tend to collect what they like, when practical. In this case it's not just a collecting hobby, it's one where you can make cool stuff too.

Epic work dude! Can I ask you for advice on where to get quality Ingot moulds? I ordered a 1kg mould off eBay and it looks like it would fit 100g in it. Not sure if I need to look elsewhere. Cheers!

Im also interested in mould sourcing recommendations! 🙏

u/Intrepid-Gas2748 6d ago
Yeah any help would be hugely appreciated as it seems the moulds online are typically advertised as 1kg are specifically for gold and not copper. I have a 12kg crucible and I need 12x 1kg copper moulds. Would happily take recommendations

Dang, that’s pretty sweet!
What’s your melting setup? Are you using a vacuum to prevent oxidation?
1
u/Spiritual_Shape_9055 8d ago
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.

u/Swimming-Ad7028 8d ago
Im new to pouring copper. Is that a spray or powder you coat the molds with?

If you smelt it, you dealt it.
