I am surprised you haven't heard about the Pyrex problems before. This has already been studied extensively and at length by Consumer Reports Magazine. It's also been reported on the news extensively. If you have older Pyrex, it should be fine. I'll link the Consumer Reports page on Pyrex and Anchor Hocking. There's a menu on the left side of the page that has all the different subtopics about Pyrex that Consumer Reports has written.

Here is a link that might be useful: Consumer Reports on Pyrex and Anchor Hocking

Nope, never heard a word! I watch news on TV and sometimes read the paper. Never heard anything. Believe me, if I'd heard about glass pans that can become "suicide bombs", so to speak, no glass cookware would have been in my house! Thanks for the link. Apparently, no glass cookware is safe. I'm 64 years old and there's enough horror out there in the world. So I don't need to have things exploding in my own house!

I have inherited some Pyrex/Anchor Hocking bakeware and also see it often at garage sales. Is there any way to tell from the markings whether it is the older 'safer' glass vs the newer material?
