I did have this happen and mine were old but not 25 years old.

I think what they're saying is that you have to go back 25 years to get true Corning Pyrex. If your Pyrex was 25 years old, you'd be safe. It would only explode if it was less than 25 years old.

Well, that's just lovely (not). It doesn't say how long before those micro-cracks develop. Maybe it's a combination of time and usage. I don't use mine daily, but I do use it at least a few times a month. I don't know how old my stuff is, either, because some things have been replaced for various reasons. So one piece might be 3 years old and another piece might be 15 years old.

What to do? I guess I'll risk it. What else is there? I bet Anchor Hocking is the same material. The frequency of it exploding is obviously rare, or it would all have been recalled - though I'm surprised it hasn't been.

mine didn't explode as described in this article but shattered when I took it out of the oven and placed it on the counter. Didn't eat the dinner that was in it for sure!!! I use mine a lot in the oven. Well I used too!!LOL

I can live without my phony pyrex.
I could NEVER live without my Guardian Service though!

All glass, no matter what type of glass, is subject to thermal shock.

I used one on top of the stove many, many years ago. it didnt' work well at all! but i didn't know not to use it there. corning ware was fine, not pyrex. but in the oven, odd.

This brought back a memory. A couple of years ago, I was cleaning out a lower cupboard. My cookware and storage containers were in it. I was taking everything out so I could clean out the cupboard and organize what had gotten messy. I had three nested Pyrex casserole dishes and because they were glass, was taking them out one by one. When I took out the second one, my hand was about 3 inches from the floor when I fumbled and dropped it. It shouldn't have broken at all, but it broke apart into a bunch of large pieces (and of course some small ones).

I remember being so surprised. It just wasn't far enough above the floor to even crack, let alone break apart like that. I remember thinking that it broke so readily. It seemed so odd at the time. Now I wonder if maybe it didn't have microfractures in it already, and maybe dropping it saved me from having it explode on me.
