If your hothead is "always in reduction" then your bead/glass is NOT in the right spot in the flame.
See the tutorial that Nikki (
www.nlcbeads.com) has on her website on where to put the beads in the flame on a hothead for more info....
For everything else, the links Dale posted are great...
Hotheads rock when used properly & you can make great beads with them...and your BBQ tank can later be used when you upgrade to something like a minicc, cricket or other "bigger" torch...
