Upon a midlife crisis near age 50, New Zealand-based artist Max Gimblett moved from the nonreferential, hard-edged geometry of his early work to a new, defining frontier of his oeuvre. In an exit from the formalist paintings he created in the "Radical Painting" group in San Francisco, Gimblett began his best known work which he painted on canvases in a variety of unconventional shapes, most notably the four-petaled quatrefoil (a shape loaded with both Eastern and Western religious symbolism.) In object-based paintings, Gimblett uses materials such as silver and gold leaf and contemporary polymers like epoxy, plaster, and resin, ultimately achieving a surface likened to porcelain. He works quickly and gesturally, armed with an extensive variety of rollers, mops, and brushes. Gimblett is also known for his Japanese ink drawings, whose gestural calligraphy informs his larger, abstract paintings.
