For my hdd cooler (see the hdd thread) I needed to bend copper sheet around copper pipe and as i dont have the proper tools for doing it I need it to be as soft as possible.
When the copper went red it was sorta a darkish red and I could see it easly but my dad had to turn the light off to see it (slightly colour blind), I think I could have got it hotter but not much, the copper was in the middle of the flame.
