Black patina for copper foil

I made the mistake of waxing my stain glass project before I used black patina. I haven't put the black patina on yet and wondered what can I do to correct my mistake. Thank you for your help. Larry
AnswerHi Larry,
Since writing the original tutorial, I have found that the wax won't cause a problem. It will remove any oxidation that could cause a problem with the patina "taking". I just finished a project and used black patina. I now wax before using black patina, and it came out a beautiful black.
I have added a note on the tutorial about wax and black patina.
I added some white vinegar to the black patina. I didn't measure anything, but it was probably about four tablespoons of patina and one tablespoon of vinegar. As I said, the black came out a beautiful deep black.
I'm sorry that if I caused you any confusion.
