Your Corning Ware 2_ Quart P-2;-B Cornflower dish WITH LID is a popular vintage cookware item. It was made between 1957 and 1988. The original pieces were crafted from Pyroceram, a glass-ceramic material that resists thermal shock. This means you can move this dish directly from the freezer to the oven or stovetop without it breaking. It measures roughly 10.5 inches from handle to handle and about 5 inches deep.
