Copper Bar Melt II

Remix of my original copper melt post, where the last bars were exclusively sheet copper this was a mix of pipe and wire copper. Produced around 19 lbs of pure copper and about 9 lbs of an unknown bronze (I had a little left over metal in my furnace and the mix produced an unknown alloy)

Burn in schedule for Devil Forge?

I got a devil Forge and got the satanite spread all over it. Is there a burn in schedule for the Forge and the crucible to get it tempered and ready to go? I'm assuming I don't just want to turn the thing on and start melting.

What's the best way to remove the black, burnt residue from objects after sand casting without changing the surface texture? Sanding is hard and changes the finish and polishing doesn't always reach all the crevices.

First copper bar

I made my first copper bar and manage to get to quite smooth looking but lost a fair bit of weight in the process. Does any one have any tips on getting the nicest finish?

First time crucible use

I'm getting into forging and metal melting as a hobby, I just have some cheap beginner equipment at the moment, I'm using a propane forge: https://a.co/d/09UWlEgF and a graphite crucible: https://a.co/d/01x6tmSC . I'm aware that you must heat treat your crucible before first use. many sources say to heat your crucible in the oven at 200C for an hour or 2 (before heating the rest of the way in the forge) but they don’t specify much. im wondering if I have to heat it up to 200 OVER the span of 2 hours or if I can just let the oven heat it up to 200 and then keep it there for 2 hours. Also once heat treated do I still have to heat it up in my forge gradually or can I be more lenient and heat it up faster.

Looking for boxing hares statues from Polish artist

2 days ago, I saw two beautiful large bronze statues of boxing hares in a small shop in Omeath, Ireland. Unfortunately, they were sold before I had the opportunity to buy them.

I was told that the sculptures may have come from a Polish artist or foundry, and I have been trying to identify the artist ever since.

The sculptures showed two hares in fighting or boxing poses. Each hare stood independently on its own base. The style was elegant and expressive, with unusually long, elongated ears rather than anatomically realistic proportions.

I am very interested in purchasing similar works, and I would be extremely grateful if you could let me know whether this description sounds familiar, or if you know the artist who created them.

Thank you very much for your time and assistance

I got one! (I was suppost to get 4)

hey better 1 then none right?

After a big shipping delay my graphite molds finally came in.

I had hoped to make lots of these zinc darts. My father calls them "little bombs" (their not)

Perhaps I'll be sanding the entrances to make the zinc flow in better. what do you guys think?

Sand Casting a Silver Ring

Hey, I wanted to share some of my progress making a ring with y'all! This community has taught me a ton about metalworking and it's really cool to be able to go from lurking to having something to show.

Context: my friend from decades ago reconnected with me and asked if I'd make him a ring! I've made a dozen or so silver rings so far, but none this big (size 15)

I was hasty with the mold, fighting off mosquitos while I shaped it, and I paid for rushing in time grinding out the flash, but ultimately I'm really happy with how it turned out.

I've experimented with smaller and smaller sprues and I've started trying to pour without any sprue at all. That didn't pan out here as I added a little more sterling at the last minute 'just in case'. Foolishness, but I'm all about working with happy accidents!

In general my idea is to pour the ring then do as little as possible to it, I let it be imperfect and strange, and I don't try to be a better artisan than whatever accidents shape the metal. Hope you enjoy!

Judge my setup before purchasing?

So I’ve been sand casting for years now, and have just been able to save up enough money to put together a shopping list for doing vacuum casting. It will also be an excuse to dip my toes into resin printing after doing FMD printer professionally for a decade now. I was hoping to get some feedback if anyone would be so inclined. I’ll list current pricing as well to see if I’m over paying or maybe getting a good deal

Kiln: Vevor 1650W Programmable Kiln- 439.99
Resin Printer: Anycubic Photon Model 4 with Wash and Cure 3.0- 266.38
Resin: Siraya Tech Royal Blue 1KG- 67.99
Investment: Prestige Oro 10lb- 34.40

Now, as for the vacuum casting “machine”, I’m trying to decide if I should go with the generic Chinese alphabet soup 3 in 1 that is rebranded a thousand times over and then buy the vacuum pump separately (machine is 399.99 shipped), or if it would be worth it to go for the Vevor 3CFM machine for 655.90. I know that Vevor isn’t exactly some shining pinnacle of quality, but they seem to be the middle ground between “you’d be better off making your own” and “you’re a professional jeweler”.

Over all, what do you think? I’d be mostly casting non-precious metals, though I do have a 10 or so ounces of silver I might make some sterling with. But I’ll primarily be working with your standard copper alloys and aluminum.

Brand new Argenta Agatronic G vacuum caster

Ok another one for sale, this one we bought in March 2026 and NEVER USED. So it's brand new.
I'm selling it with the busch R5 vacuum pump

price is 9k €

comes with a starter kit and 2 flasks, and i'll throw in all the spruing wax i have

Would prefer a pickup but can ship.

this machine is pretty cool because it uses argon, it's low tech, but high performance. I like machines that don't break. Schulthiess / indutherm, yeah they are great but I only had issues with them over the years.
Look on youtube or facebook then you can see what kind of trees you can do with this machine.
You can even make granules

Video call for serious inquiries. I run a small casting company in Switzerland
