This is a vintage Pyrosil Ware Corning casserole dish with a 2.5 quart capacity. The dish is square-shaped with a black trefoil scroll pattern on a glossy ceramic coating. It comes with a lid and 2 handles, and is made of glass and ceramic material. The dish is flat-bottomed, freezer and oven-safe, and easy to clean. It weighs 3lbs 8oz and measures 9.5" in length, 7" in width, and 4" in depth. The backstamp is printed, and it is an original product. It could use a good cleaning.
