I had to do 5 samples today, they took 3 minutes apiece to heat with
my good heat gun. I can see how to do it better now.

I just heated a 1/4" spot on a black plastic brush handle
molten/smoking hot in less than a minute with a 50W Halogen reflector
bulb, a Sylvania PAR20. There's a focal point less than an inch from
the face.
