[TheForge] Copper Brush

[Michael H. Murphy]

I'm not really sure what the exact temperature is, but when the brass comes
off the brush onto the steel without discoloring, that's the right heat.

BTW, wouldn't you say that any heat from about 150 up to where you can see
it glow could be defined as a "black heat"?
