Transform your favorite dishes with high-performing, naturally non stick French porcelain. Our Bakeware begins with a 202-year-old recipe held secret by skilled artisans in the Loire Valley. The finest and most precious of all bakeware materials, it is also the most demanding to produce. Porcelain provides a naturally non stick surface and even heating, ensuring crisp corners and gooey middles without over or underbaking. Ours is microwave- and oven-safe to 650F and thermal shock resistant, meaning it can go from freezer to oven to table.
