Pyrex and Anchor Hocking Glass Baking Dishes

I am a big fan of glass baking dishes and learned something very disturbing in this month's Consumer Reports magazine.  The formula for the Pyrex and Anchor Hocking glass baking dishes changed in the mid 80's and the new formula doesn't hold up as well as the original formula.  If you have ever had a glass baking dish shatter, it might not have been something you did, it could have been because you have one of the dishes made with the new formula.  Consumer Reports tested dishes by placing them in a 450 degree oven for 80 minutes and then taking them out and placing them on a marble counter.  Every single one shattered.  When placed on a towel which buffered the cool surface, they did not break.  Essentially, you have to read the instructions and follow them closely.  The newer formula is not as sturdy as the older formula.  Now, I am going to be leery about using my glass baking dishes.

  1. That happened to me-shattered INSIDE the oven. I was cleaning chicken grease for months.
