Relief Collection Earthy pots and vases inspired by seeds, barnacles, pebbles and other natural wonders glazed in rich hues. Jonathan throws each prototype and then creates the relief by masking off the patterns and sponging away the exposed clay. Jonathan Adler pottery begins its life in our Soho studio, where Jonathan and his team design and sculpt every prototype. The product you are viewing is produced by skilled artisans at our main workshop in Peru. They make molds from our prototypes and then hand craft each piece from high-fired stoneware or porcelain. Our Peruvian workshop was found through Aid to Artisans, a non-profit organization that connects designers in America with artisans in developing countries to promote fair trade. High-fired stoneware with a matte jade glaze. 3.5" High x 3" wide.
