Making a Bronze Bowl - DIY Metal-Casting

I melted down silicon bronze and made a bowl out of it! Blog post at: 300mpg.org/2024/01/22/bronze-...

Lately, I've been trying my hand at some hobbyist metal-casting. I created a few projects in brass and then switched over to bronze. (Brass has Zinc, which easily boils off into Zinc fumes! Something I don't want to breath!)
I tried making a copy of a small bowl my wife has. I used it to create a sand-mold, then melted copper and silicon together in my #vevor forge. I then poured the metal into mold. While it took two tries, I had a pretty good copy. I ground off the flashing and polished up the interior.
I finished the outside of the bowl by heating it and brushing on Liver of Sulfur. That is an oxidizer which turns the bronze a dark gray. Then I polished back the highlights with 0000 steel wool.
Tools and materials for this project:
Vevor Propane Forge: amzn.to/3S7msY4
Crucible: amzn.to/42fV8vy
Liver of Sulfur: amzn.to/3u42Yvu
Talc (Parting agent) amzn.to/4b9wj8k
The metal is "Silicon Bronze". This was a mix of 95% recycled/scrap Copper and 5% elemental Silicon.
The sand I used for casting is playground sand, sifted, mixed with about 10% crushed clay kitty litter and just enough water to make it stick together.

Other than EVs, my other hobbies have a common theme of fermented foods. It started innocently with bread, then kefir, beer, then wine and now, I ferment my own cheese. Love them all!

I've only ever tried cheese-making once, but I'm not bad at baking!
It's good to have hobbies!
I'm always interested in how things work, whether it's electric motors or how to alloy metals!
PS: I've done some pretty decent yogurt-making too!
