CorningWare is a brand of stoneware bakeware, used for preparing, serving and reheating food. If you use the cooking and care instructions suggested by the manufacturer, your CorningWare should last you for many years and provide consistent cooking results. Although durable, some situations will result in breakage of your CorningWare product.
Ensure the CorningWare item you are using is appropriate for your cooking application by looking at the bottom of the piece. It will be stamped with information about appropriate use (convection, microwave, conventional oven). Vintage CorningWare pieces (heavy, with a cornflower blue graphic) are safe for use on the stove top as well.
Preheat your oven, unless you are using a microwave. Sudden temperature changes can cause shattering.
Ensure the food you are preparing adequately fills the dish, as a dish that is not full enough can break.
Prepare your item in the CorningWare as desired, so long as it is indicated on the bottom of the dish.
Use care when removing your CorningWare from the oven, using a dry towel or oven mitts and never a wet rag. Set it on a cork trivet when possible instead of the bare table or counte-rtop.
Allow cookware to cool slightly before placing it inside the refrigerator for food storage.
Clean using a non-abrasive cloth or sponge. Never immerse a hot dish item in water, and avoid soaking to clean.
