Porcelain can chip if dropped, however this does not reduce the effectiveness of the cookware. There are no PTFEâs, PFOAâs or any other chemicals to change the taste, color or nutritional value of the food. Just the right size for empty nesters, singles, college students or use in a second home. A smaller version of the traditional casserole. Perfect for cooking your favorite dishes in smaller portions or use to cook and serve side dishes. Includes Lid and capacity is 3 quarts.
