So I found the "mini metal foundry" on indestructables and elsewhere I see guides for similar foundrys. Now they all say to use a 10 quart steel pail. Now most of them say a galvanized steel pail is fine. I guess since it's insulated with the plaster and play sand the pail itself never gets hot enough? Because I know galvanized steel will fuck your shit right up if it gets hot enough with the fumes.
Anyone have any opinions on this?
I made one with a galvanized steel bucket. The outside definitely gets too hot to hold bare handed, but it barely discolors. Definitely not enough to release enough fumes to fuck your shit up.

excellent, good to know. DO you know how stainless steel would do? I'm not sure at what temp it gets all fucky with chromium fumes. I have an old industrial coffee thermos I was thinking about using.

Holy shit. I just realised how many stainless cylindrical things I've scrapped.
Thanks for the idea.

So it should be fine then? Not gonna give myself chromium poisoning?
I made this mini furnace just last year, with the exact same steps in the video. I knew that the zinc plating would lead to metal fume fever, so I put on a gas mask and sanded down the bucket. Sanding the zinc coating off would create zinc particulates that are obviously harmful if you breath it in, but you should be good with a good mask. I'd imagine that the particulates wouldn't get through, but the fumes would.

Zinc only burns at red heat or so. The outside of your bucket isn't going to get that hot. Besides, zinc oxide isn't all that terrible. It's not a cumulative poison and you only have trouble if you breathe a ton in. Basically if you see white smoke just hold your breath and move away from it, like you would for any other plume of smoke.
