Had quite an incident the other evening. I was working at the computer and the wife was making dinner. She had marinated chicken breasts and baked them in her pyrex glass pan. She turned on the broiler for a minute or 2 just to glaze them as she always does. I heard her open the oven door and then I heard a loud POP and her scream. I ran to the kitchen to find her standing there with glass all around her. Luckily she didn't get burned or cut and most of the glass fell onto the oven door. She has always done chicken breasts this way in her pyrex and has never had this happen before, I can only assume age and the sudden change in temperature caused the pyrex to explode. Be careful when baking with this stuff!
