I am attempting to patinate some fine silver (1/8") strips. Any
suggestions, other than liver of sulphur, that I can use for this
purpose?. Would love to incorporate colors such as purples, green,
yellow, blue, into some of my designs.
Try liver of sulphur with the recipe by Katherine P., published in
an article here at orchid.
You can get purple, gold, yellows and browns.
Otherwise, look into SculptNuveau.
