How to handle a HOT HEAD?
I have a hot head that I want to take to occasional shows, I use MAP gas with it, but I can barely melt soft glass with it. Also, it makes light colored glass dirty looking. What am I doing wrong, or is this all I can get it to do? I knopwthat some of you have used this torch successfully. HELP!! Please!

If it makes glass dirty and you have not enough heat with HH its probably where you are working in flame and how you have flame adjusted...
Ideally HH should be able to adjust so you have a sharp pencil point of light blue flame in main flame cone, but most new HH 's have poor fuel control so do best you can with flame adjustment... Big bushy out of control flame is not your friend...
Next thing is where you are working glass in flame, if you are to close into flame you are getting a lot of unburned carbons in your flame and they are sticking to your glass... Try moving out in flame a bit more, best zone is usually 2 to 3 inches from metal tip of burner right where you should have the bright blue pencil point flame.... There is where combustion is most complete (cleanest) and flame as at it hottest...

Generally you want to work with the torch turned down nearly as far as it will go without going out.

For safety sake, are you sure you want to take a torch to a show? I am telling you that people are almost as stupid as they are curious. Look into Insurance before you decide to do this, as well as planning to block off a safe area so folks don't singe their eyebrows- or worse.
Additionally, if you're torching outside, the sun is going to make the flame difficult to see. If you're indoors, you have tank issues.... are you on canisters or are you planning to use a larger bbq type tank? Again, check on insurance before you do this.
Don't forget to get clearance from the Fire Dept., as well.

I plan to work outside under a canopy, and I will make sure that I have the area blocked to keep people a safe distance. Thanks for all the tips!

I saw someone do a demo with a hot head at a show and they used plexiglass on 3 sides so viewers could not get burned. Worked great!

Actually neither.... You have to adjust flame for its optimum shape and heat, and then find best working positions....
Turning down flame as low as it will go just makes a cooler flame.... Not enough fuel makes a oxidizing (or neutral) flame as HH always seem to be fuel rich.....
