Exterior Facade Finish | Oxidized silver, commonly found in jewelry, is a darkening process that imitates the natural tarnishing process. This process offers a great charcoal detailing over the sterling silver and a real sense of depth. We have taken this beautiful charcoal oxide layer and mixed it in pearl ink, applied it over silver pearl, added a bit of natural light changing pearl, and brushed this on top of a clear coated aluminum. The result is deep color, great depth and a very antique, tarnished grey.
