The Corning Ware P-309 Pie Plate in Blue Cornflower is a vintage piece of bakeware from the United States. It features a classic round shape with a white base and a beautiful blue cornflower pattern. This pie plate is made of ceramic and is suitable for use in electric, gas, and microwave ovens. The glossy finish and mid-century modern style make it a charming addition to any kitchen. It is dishwasher, oven-safe, and microwaveable, making it both practical and convenient for everyday use. Never used.
