I'm not an expert, but when I wanted to play with fire, people talked me
out of using my Dragon's Breath torch (as Bill noted), and instead
recommended a MAPPro torch instead.  What I found is that the MAPPro flame
is small and narrow, like a propane torch, but hotter.  You can get closer
to the flame, and need less fire bricks that way.

The Dragon's Breath, while bigger in terms of BTUs, isn't as well
controlled, and I'd probably need a much safer place to work than on top of
a Workmate with 4 fire bricks.
