'jiggy.....
I pour all mine outdoors. I try to dodge the smoke too. I'm working on a set up in my spare apartment ( 2F house). I 'm going to run a range hood & then maybe hang some canvas or something off it so ALL the fumes go out. I have close to 20 molds, and it's really a pain to take the pot out on the porch, all the hooks & usually when I pour, I keep at it about 8 hours or so. I like to do enough so I don't have to do it again for awhile. I usually only use about 5 molds, but have to alternate. If you pour in an enclosed space, use ventilation, ie. fan in a window & set the pot up near the fan.
It can be dangerous, so be sure to wear gloves- leather work gloves , goggles are recommended too. NEVER - ever put any water in your pot----like a pipe that has a few drops in it !!
