Copper residue in the mix. What are you using as the rusting component? What process did you use to strike up the barrels and get them ready for the process? What solution?

Ive tried Laurel Mountain solution; I always seem to get copper colored splotches when using it. I believe that they use copper sulfate in their solution. Guess I was doing it wrong.

Tony first, then Mike answered the copper residue spots problem in these posts I believe......I agree with their posts and conclusions.....
I have found that Mark Lee's products are superior to any other that I have tried, for blue or black or brown, damascus or fluid steel......his products also lack toxic mercury, which nobody needs......
Acetone is used to clean the barrels
before any boiling is applied.......to repeat my post above more clearly:
I clean thoroughly with acetone, including inside the weep holes.........let the acetone evaporate, look for residue on the barrels and re-clean with acetone if necessary, then boil in clean water for at least 10 minutes and then look for any residue in the water or on the barrels, then change the water/clean the tank and repeat the pre-boil if necessary before applying the rust blueing........
Good pre-clean with proper preparation + using excellent rusting products = very nice professional rust blue/black/brown surfaces........
