No second-hand accounts, please, because they tend to acquire embellishment along the way or the facts are tainted, i.e.: accidentally using Pyrex amber bakeware (which was sold for a short time to compliment VISIONS and was clearly labeled "NO STOVETOP OR BROILER") on the stove.

Similarly, don't confuse mid-20th century white Pyrex with Corning Ware Pyroceram.

Lastly, stories about chipped, cracked or otherwise structurally compromised cookware don't count.

Cracked cast iron has been known to explode but no one's circulating internet rumors as gospel truth about the "dangers" of cast iron.

Do not use to microwave popcorn or to hold or support popcorn bags, microwave convenience foods with special browning wrappers, etc. Do not use or repair any item that is chipped, cracked or severely scratched.Product defects do occur but I'm referring to the widely circulated accounts of a carefully maintained item breaking from normal cooking temperatures or minor thermal shock (less than glass-ceramic's threshold of 840 degrees F) as a reason to throw the stuff away and pull it off the market.I don't work for World Kitchen and never worked for Corning but I have a feeling if you track down the truth, you'll find misuse, abuse and negligence as the root causes, not a manufactured-in "tendency" to failure. When I was a kid, I blew up a piece of Corningware in the microwave.Use the glass lids for cooking and serving, and the plastic lids for storage.Limited One Year Warranty- Corning Ware® stoneware bakeware.
