This is a CorningWare Blue Cornflower casserole dish (two-handled pot). Born in 1958, it's a cooking utensil made of "Pyroceram," an extremely heat-resistant glass. It can be used on direct heat, in the oven, and in the microwave, and features a practical design that allows you to take it directly from the kitchen to the table. It's good at retaining heat, making it suitable for residual heat cooking. No original box included.
