Most of my jewelry that I make, I add a patina to. I just like the warm earthy look of a piece after it has been oxidized. I use liver of sulfur, and boy does it stink. I found a tutorial on…The earrings in the tutorial have a gorgeous blue colored patina. They are really pretty. But just like when using LOS, you will need to be in a well ventilated area, because you will be using household ammonia.
