So it's my first day making beads...i have devardi glass. A hothead torch and a small $3 canister of propane. My beads are burning and the flame from the torch has a lot of orange. Shouldn't it be all blue? I don't like burnt beads...i even tried a slower heating rather than shoving the glass in but i can't get it to wrap on the mandrel till it glows orange??? Please help i want to make great beads
