[WWI] Annealing Question

[Fred Hultberg]

It doesn't matter whether the part itself gets visibly red hot(dull red, let me be clear on that), because the parts are so little mass that they will assume the temperature of their surroundings very quickly.
 
You may not be able to see the part "being dull red" but when the iron plate is dull red(clear on that? DULL RED!), the part(s) will be also. Of course, you're working in a fairly dark room, I hope. Wizardry - really looks Alchemic(Medieval?) in nature!
 
I cannot recommend using a cigarette litgher or other flame as their heat is too localised. While you see "yellow," bear in mind that the yellow is more visible that the blue that goes with it. Blue is much too hot - it's what they use for melting Iron and Steel. Very hard to control the flame, but if you've had success I will back away and watch your parts vaporise some day(voice of bitter expreience, there).
 
All for now.
 
yours
