Hello List, It is lonely in here lately, guess we need a new fall. But,
anyways, I etched my first iron. It is a campo end cut. I thought I would
try Ferric chloride on it. Norton talks good about it in his newest book. I
applied the Ferric chloride and within 30 seconds patterns appeared so I
stopped it right then. I don't know if this was the right thing to do. Is
that when you stop or should it go longer to get a better etch?
Thanks, Tom
