Have found someone who is interested in my burnout ovens, casting machine & torch, but he doesn't have natural gas at his building. He wants to do jewelery, so I'm casting gold and silver.
The only alternates I can think of is propane or acetylene, but my old memory says they burn too dirty.
Please, what are options?

Thanks all

Actually natural gas burns dirty and propane burns clean.

Propane has worked for me in the past as well as other of my lab friends. Hopefully the building fire code would allow for a small tank of it?

He can use oxygen/propane just fine,the acetelene will be too sooty.

Depending on the locality, they may have to put a propane tank outside and pipe it in like is done with a propane range/stove in homes. But propane/oxy is perfectly fine for casting anything but titanium.

I use propane. The torch is from Renfort. I just use the little green bottles.

Thanks all.
It'll be interesting. He wants to teach jewelry at a charter high school that is located in a still functional wood working mill. The Blu Ox Millworks has an impressive history, and if he can add lost wax casting to the school curriculum, wow

If hes just doing small occasional stuff, bottles of Butane would work fine. Burns cooler than Propane or Map.
