The present lot demonstrates the emergence of Eva's design ideology of "the playful search for beauty". Her goal with the Cloverware series was twofold: to create "free, lively forms in plastic" and to introduce these newly developed acrylics as a suitable material for tableware. Zeisel created 15 distinctly biomorphic shapes in three richly colored hues. The edges glow with reflected light. During World War II, the Clover Box Company had made plastic windshields for fighter planes and were looking for a new project after the war. Zeisel and the owner experimented until they came up with a new production technique; she cut a shape, the top view of the pieces, out a piece of plywood. Then they laid a flat piece of acrylic plastic on top of it. They warmed the plastic until it sagged and then used an air pump to pull it down from below. No molds were used to create these shapes.
