A while back on this forum someone mention that case coloring could be somewhat restored using coldblueing and a torch if done correctly. Any one know how do do this method?....Thanks....Hutt

As in the case hardening of the firearm frame? For a firearm you intend to fire or which someone else may end up firing?

You can heat steel with a torch to reach color hardening temperatures. You will end up with the sort of colors you see on some motorcycle exhaust systems. Very pretty. I suspect you'll also render the gun unsafe to fire.

I agree.

Color case hardening is there for the hardening, not the pretty colors.
It's just a by-product of the hardening process.

Leave the torch in the plumbers shop where it belongs before you ruin your gun, or worse, make it unsafe to fire.

I am not trying to get the reciever red hot. There is a method useing cold blue and limited use of torch flame heat. I have seen results although it does eventually wear off.
