Corning Ware 10" casserole with cover from Corning Glass's Blue Cornflower series. This is the original Corning Ware Pyroceram glass and ceramic material that can go from freezer to oven to table top. The CorningWare411 site states that the format of the P-10-B back stamp dates this dish from 1961 to 1966.
The casserole and cover are in very good condition with no chips or cracks. The dish does have some utensil marks and random black marks along the rim and on the handles from use. This is perfect for use on the stove top burner, in the gas or electric oven, and even the microwave oven.
