All this has gotten me thinking. Rather than using my kiln, I'm considering using the burner I use for my vertical barrel boiling tank. It's a high output wok burner using natural gas. It's in my basement, so I've ordered a higher CFM exhaust fan for my ventilation system. I have a large cast iron Dutch Oven to put the salts or lead in. It should be able to go up to 830 with no problem. I should be able to shoot the temp easily with my infrared thermometer.

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
