Red Concave Circle

Red Concave Circle

In the late 1960s and early 1970s, De Wain Valentine experimented with polyester resin, working with industrial plastics companies to develop innovative formulas and chemical processes that allowed him to cast much larger pieces than previously possible. With a diameter of eight feet, Red Concave Circle is a rare example of Valentine’s large-scale disks. Twelve inches thick, the circle contains dense pigment at the periphery and is more translucent towards the center. At once transparent and reflective, the sculpture creates unique optical effects that distort the viewer’s perception of the surrounding environment. Valentine cites the expansive skies and ocean waters of the West Coast as phenomena that have influenced the translucent qualities and materials of his sculptures.
