Reading both ancient and modern, this decorative disc metal wall art has the intriguing appeal of a found object. Made of cast aluminum, the disc is partially etched with concentric circles of intricately texture. Its rich, rainbow patina is created by plating the disc in brass then dipping it into acid to oxidize its surface. Completely black when removed from the dip, the disc is scrubbed to reveal the underlying finish and give it its one-of-a-kind glow.
