Our durable stoneware Au Gratin Ovenware diffuses heat slowly and allows flavors and aromas to develop naturally. We create the ovenware by attaching two different knobs to the ovenware form when it is just removed from the mold. During the firing cycle the bond is made permanent. Each piece is handcrafted from a speckled stoneware clay and glazed to perfection. No two are alike. Created in 6 glossy colors and 3 sizes.
