[TheForge] Etching Damascus

[Washington, Aubrey O.]

Roger,
 
How do you use pH Minus with copper?  Do you quench/anneal the hot copper in it?  Does it keep the copper bright or does it give a patina?
 
Aubrey

The PH minus is what a bunch of use who do copper vases are using as the
pickle and quench solution for the anneal.
I think we have Tom Latane' convinced to switch from high strength
vinegar to the ph minus for his descale soak for his steel work between
the forging operation and the filing stage.
