ELK Lighting - ELK Lighting 771-MB Santa Fe 1 Light Wall Sconces in Mission Bronze - Using a color palette that gives a nod toward the West, the Santa Fe series combines patterned Tiffany glass with genuine curved mica panels. These mica panels start off as large rock-like mineral deposits that are mined from the earth. Through a careful process of cutting, polishing, and color dyeing, these deposits are made into thin sheets of translucent amber mica, characterized by its trademark cross-hatched pattern of silicate minerals. The result is a unique blend of materials that compliments its Mission Bronze finished framework in the true Arts and Crafts style.
