Throughout her career, Helen Pashgian has made sculpture out of various plastics and resins. She is one of a group of Southern California​ artists—​known as Light and Space artists—who have created works investigating perceptual phenomena: how we come to understand form, volume, presence and absence through light, seen directly through other materials, reflected, or refracted. Untitled (Wall Sculpture) is made of copper and cast epoxy resin. In conjunction, the two materials create a beautiful play of reflected and refracted light and an illusion of great depth, despite the fact that the work is in fact only three-and-a-half inches deep. This sculpture highlights Pashgian’s mastery of plastic materials to create compelling visual experiences involving light and an understanding of both real and assumed space.
