ProductDescriptionPYREX glassware is incredibly durable and easy to clean. Unlike earthenware, porcelain or enameled dishes, PYREX glass absorbs, rather than reflects oven heat waves. This speeds the cooking process and helps save energy. It's a durable and practical form of cookware that's easy to clean and attractive to serve with. PYREX glassware products can go directly from refrigerator or freezer to a microwave, convection, or preheated conventional oven. A small amount of liquid should be added to the ovenware vessel prior to baking foods that release liquids while cooking.
Love these! I own several sizes of these storage bowls and love them. They are sturdy, look good in the 'frig and on the table plus allow me to use them in the microwave without worrying about chemicals leeching into our food. The lids have been washed repeatedly in the top rack of our dishwasher and have held up well so far. Yes, they are spendier, but worth it. Also, I got mine during an Amazon special so managed to pay a more palatable amount.
