This is my first experiment with copper leaf and green patina. I thought it would turn green almost immediately, NOT. So I would lay the patina soaked rag on the bowl for thirty seconds or so and it still didn't turn green. It kind of etched the surface where it is dark green. I was so disappointed and went in the house and told my wife it was a dismal failure. I went out the next day to sand the copper off to start over and found to my surprise it had turned dark green. I'm not sure what happened where the bright copper spots are. I'm real interested in trying it again on another vessel. It took awhile for it to dye the copper green. I sprayed it with a couple coats of Krylon Crystal Clear Acrylic and finished it off with Krylon Matt Finish, sanded with 600 grit to smooth it out. 4.5"H x 8"D
