[TheForge] Re: Bricks- Light vs heavy

[Lynn Emrich]

I jumped on the slow cooling bricks because I have had
trouble annealing thin stock in the past. I did
everything I've always done. As example I would
normalize, heat to nonmagnetic + some and air cool
more than once, than heat to critical bury in pearlite
for cooling. The thin stock, in this case some power
hack saw blades a customer wanted a knife made of, and
when drilling had problems. 
I haven't had thin stock to anneal lately so it hasn't
been a problem but the bricks seems to be better than
some of my past techniques. Heating to critical and
drooping to the bottom of my Don Fogg type forge and
turning off the gas. Not correct but quick and easy.
