Early in our marriage, my husband, the science teacher, put a Pyrex container of left-overs on the gas stove. It shattered, rice and glass shards shot all over the place. He did manage to clean it up. (I don't know how he did it, but I truly admire that.) I asked him what he was thinking, and it was that his beakers in the lab were Pyrex made by Corning and they went on the Bunson burners all of the time. How can I gripe at him about that? I just explained that cooking and lab equipment were made for different purposes, and he said he had just learned that.
I got an email years later - one of those that are full of misinformation, usually - about different years and Pyrex. I checked on Snopes at the time, and it seemed to confirm the email. I just looked for it again, and Snopes seems to be not quite so sure - check 'Exploding Pyrex' in their search. I do remember that the Pyrex in question was about the new stuff and mine was old.
I've always known not to shock Pyrex, like putting it from the oven onto a damp cloth.
