My ex fiance is heavily into it. She both buys from vendors and makes her own glass beads with a torch. But I REALLY don't want to contact her right now. She's still pissed off.
eta I actually set up her torch and oxygen system for her. Lots of specialty tools, can get quite expensive for initial outlay if you buy from the artsy sites. There are a TON of free demonstration/how to videos out there on the net.
If you go the roll your own route the big items you will need are a propane tank, a small desk top propane torch and an oxygen source. I set her up with a refurbished medical oxygen generator, the kind that COPD patients use at home. A kiln is required to fire the beads, they make tabletop models, they ain't cheap. You could probably get a used pottery kiln that MIGHT be sufficient, I don't really know. If I think of any other key points I'll update if you're interested.
