Our unglazed stoneware is made with our new StoneFusion material making it our strongest and most durable stoneware yet. You can pre-heat, broil, and even put it in the dishwasher. Each piece features a ribbon pattern, so you can easily distinguish from your original unglazed stones. Like all our stones, you can use it to make your favorite baked goods, frozen foods, or reheated leftovers that are just as good or better than day one. And it only gets better with age. A nonstick seasoning will develop as you use it—the darker it looks, the better it cooks! Made in the USA PRODUCT DETAILS 12” x 15” (30 cm x 38 cm). Microwave-, freezer, oven-, dishwasher-, and broiler-safe to 550°F
