In the 1960s, Larry Bell broke new ground in contemporary sculpture with his illusionistic glass boxes and large-scaled sculptures. These pieces were executed in plate glass that was made highly reflective with thin coatings of vaporized metal. In this panel, or painting, vaporized metals are used to create the central image on several panels of layered glass. Light shifts and refracts among the particles on the vacuum-coated surface, causing colors to iridesce from gold or silver to blue or violet, The glass is surrounded by black denim, which absorbs light. For Bell, the behavior of reflected and absorbed light is the subject of this work.
