Corning Ware Microwave Rack, MR-1, made with the original Pyroceram material that can go from freezer, to oven, to table and is much sturdier than the modern stoneware Corning Ware. This simple rack is ~9″ x ~6-1/2″ and ~3/4″ high and is perfect for microwaving foods that drip so that the food isn’t swimming in grease or drippings, such as bacon! It is marked MR-1 and is in very good condition with little wear and no chips or cracks. Be sure to use it with the flat side down!
