From Morning Sky Jewelry: "I do a lot of work in copper and I go back and forth between liking it most in its natural shiny state and adding a patina to it so it looks darker and aged. There are examples in the photo to the right of the copper both ways. A lot of artists use liver of sulphur to add patina, but I don't have a source close by and I really didn't want the odor and fumes in my house. I don't have a separate shop with a ventilation system so I looked into alternative methods. After much research and discussion on various forums I decided to give the egg method a try."
