Pillivuyt Porcelain Rectangular Roasters,Roaster\, No. 0,

French cooks often roast meats and poultry in a deep porcelain dish as opposed to a metal one because porcelain conducts heat gently and evenly and is easy to clean. Our dish is also useful for other foods that require a deep pan - be it a vegetable casserole or a fresh-fruit crisp. The underside is left unglazed for maximum heat absorption. Made in France by Pillivuyt, makers of fine porcelain since 1818. Crafted of high-fired porcelain. Microwavable; oven, freezer and dishwasher safe. Commercial Grade: Thoughtfully designed and expertly engineered to meet rigorous standards and best practices from select commercial testing.
