Well if you're making glass beads you need something HOT to melt the glass... I use a Nortel Minor Burner which is a fairly standard entry torch.
Propane and oxygen are mixed at the surface of the torch to produce a hot flame, one that is hot enough to melt glass so I can make my beads.
The torch has two valves, so I can control how much propane (red valve on the top) and how much oxygen (silver valve on the side) are fed into the flame at any given time.
When you make glass beads it's not only how much heat and how it's applied that you need to think about but also the ratio of the gasses you use to produce certain effects, most of the time you work with a Neutral flame, but sometimes you need to add more propane (or reduce the oxygen) to make a Reducing flame or vice versa to produce an Oxygen rich flame.
I did worry I was going to blow myself up or set fire to everything when I first started... however I always remember it's Propane on 1st, Oxygen on 2nd, Oxygen off 1st, Propane off last.... and that is how you POOP safely!
What important info do you need to remember for your hobbies?
