Just read that they changed their formula in the 90s, and now it's nowhere near as resistant to temperature changes as it used to be.

I just bought a new Pyrex baking dish yesterday for casseroles. Should I return it and just get one made out of ceramic?

Anyone have an issue with this? Or am I overthinking? If I take a hot mixture and put it into the dish before going into the oven, will that cause the thing to explode on me? I've seen some pics/stories online that look pretty bad.
