Kitchen nightmares: New reports of Pyrex glass dishes shattering


After a brand new Pyrex glass dish exploded in Clark Howard’s kitchen recently, we’re learning about new cases of shattering bakeware.

Clark said a chili tortilla bake was cooked in the dish at 375 degrees for 25 minutes. After cooling for five minutes, it was moved to the dinner table.

The bakeware shattered into a zillion pieces about 15 minutes later, sending shards of glass everywhere.

Exploding Pyrex: More cases of shattering glass

“All of a sudden, there was a loud explosion. Everybody closed their eyes for an instant and then opened our eyes back up and we’re all covered in glass,” Clark recounted on the radio show. “I’ve never heard or seen anything like it in my life.”

There were no serious injuries, though a piece of glass bounced off the edge of Clark’s 11-year-old son’s eye.

We shared Clark’s story on our Facebook page and more than 500 people left comments, with many of them saying the exact same thing happened to them.

There are also similar nightmare accounts posted to Pyrex’s Facebook page on a regular basis.

How to keep glass bakeware from shattering

If you have glass bakeware in your kitchen, it’s important to follow the instructions on the packaging to prevent the glass from breaking due to abrupt temperature changes.

Here are all of the warnings posted on Pyrex’s website:

  1. Avoid sudden temperature changes to glassware.
  2. DO NOT add liquid to hot glassware; place hot glassware on a wet or cool surface, directly on countertop or metal surface, or in sink; or handle hot glassware with wet cloth.
  3. Allow hot glassware to cool on a cooling rack, potholder or dry cloth. Be sure to allow hot glassware to cool as provided above before washing, refrigerating or freezing.
  4. Oven must be preheated before inserting glassware.
  5. DO NOT use on or under a flame or other direct heat source, including on a stove top, under a broiler, on a grill or in a toaster oven.
  6. Add a small amount of liquid sufficient to cover the bottom of the dish prior to cooking foods that may release liquid.
  7. Avoid handling hot glassware (including ware with silicone gripping surfaces) without dry potholders.
  8. Avoid microwave misuse. DO NOT use glassware to microwave popcorn or foods wrapped in heat-concentrating material (such as special browning wrappers), heat empty or nearly empty glassware in microwave, or overheat oil or butter in microwave (use minimum amount of cooking time).
  9. Be careful when handling broken glass because pieces may be extremely sharp and difficult to locate.
  10. Handling your glassware without an appropriate degree of care could result in breakage, chipping, cracking or severe scratching.
  11. DO NOT use or repair any glassware that is chipped, cracked or severely scratched.
  12. DO NOT drop or hit glassware against a hard object or strike utensils against it.
