My 1st go at green patina was not a success, as in it did not patina.I think my black base was too dry. I used Walker black underglaze. Will try again. Maybe another coat of black will help. Or can you suggest a better flat black. In saying that, I absolutely love the gold on black and decided not to change that one. Can’t wait to try the rapid rust. I love the U tube on how to do it. So well explained.
