How to prevent Pyrex glass dish from exploding

Exploding Pyrex? I didn’t realize this was a thing, but apparently it can be, particularly in the U.S. where Pyrex glass manufacturing ingredients are different for some reason (regulation?) from European products. Below is frugality guru Clark Howard‘s account of what happened to him and his family. He doesn’t provide any advice in the video, just a description of the aftermath. Below the video is some advice on how to reduce the chances of your Pyrex glassware shattering like Clark’s. This advice comes mostly from the makers of Pyrex via Epicurious.

  • AVOID sudden temperature changes to glassware.
  • DO NOT add liquid to hot glassware;
  • DO NOT place hot glassware on a wet or cool surface, directly on counter-top or metal surface, or in sink;
  • DO NOT handle hot glassware with wet cloth. (The all-caps emphasis is theirs.)
  • DO NOT cook a dry dish in glass pan. Add a small amount of liquid sufficient to cover the bottom of the dish prior to cooking foods that may release liquid.
  • DO NOT use glass cookware to reheat dry foods.

Basically, avoid putting hot cookware in contact with anything cool; and avoid cooking without a layer of liquid covering the bottom of the glassware. Even Pyrex glass will shatter in those conditions.
