These are the finishes. Natural copper is like a penny, a pinkish-tan color. This will darken to a chocolate brown for the first 2 to 10 years. The Bronze finish is a result of hand-rubbing chemicals in my special process to create a classic golden-brown color on the copper. The realistic greenish-gray Verdigris finish on my products is a result of a custom-formulated chemical treatment that is hand rubbed for an authentic look. Over time, the elements will work their magic and turn the natural and the chemically treated Bronze and Verdigris finishes into authentic weathered Verdigris. Gold refers to a true 23karat gold finish applied by leafing and burnishing the surface. Confused? Click here for a color chart.
