Verdigris Cup Brass Ring
A tiny concave cup made from brass sheet is soldered to brass wire to form a cool ring that doubles as a tiny bird bath. (😉) The cup is formed by pounding circles out of 20 gauge brass sheet and then using a dapping tool to hammer the circle into a dome shape. I've then given the inside of the cup a verdigris green patina, and sealed it with clear acrylic. It can really fool the eye, because from a distance, it looks like a rounded turquoise cabochon ring.
