Why does everyone heat treat blind on a coal forge?
Last week I watched a guy at a hammer-in try to normalize a 1095 blade right in the coals and couldn't see color for half the stroke. I've ruined three knives myself doing that before I switched to a propane forge with a dark background. Is there a trick I'm missing for judging color in direct sunlight or do people just accept the guesswork?

Used to think coal was fine for heat treat until I cooked a W2 blade into a potato chip. Now I just use a pipe with a torch and a piece of firebrick behind it.

Trick I use is a dark piece of steel behind the blade, helps me see color way better.
