I am looking forward to your video. The dropping glass video was great.

I've heard of this happening and it really scares me. I wonder what conditions are necessary for this to happen to a toy. Most likely conditions that make the toy unusable, really really hot or below freezing, but still...

Pyrex used to be borosilicate glass, which is extremely resistant to temperature changes and breaks in a controlled manner. It's what's used in laboratory glassware, the kind that you can melt, bend, and use without having to anneal.

It seems that a few years ago Corning sold Pyrex or was bought, and now it's no longer borosilicate, and I suspect it isn't even really tempered. I had one go in the kitchen and it did the non-tempered shards rather then the tempered glass chunks. I haven't really trusted it since unless I know it's the old, tempered borosilicate stuff.

its the extremes in temperature.

It doesn't make me scared of glass toys as you would never try to use a sex toy heated or cooled to the kind of extremes needed for it to crack let alone explode.

But boy do I understand how freaky it would be to have your cookware explode!!

Thank you. That never occurred to me.

The heat differential was still great. Water from the tap, even if it's really hot rarely gets above 120 to 130 degrees F. (And should be lower if you have small children in the house to prevent accidental scalding.) Dishes can come out of an oven at as hot as 400 to 500 degrees F.

Although the water felt hot, it was far from the temperature of the pan.


And when Pyrex says "freezer to oven" they mean freezer to COLD oven, then warm them both slowly. I still never put anything directly from the freezer into the oven.

Yikes that's scary, I think I'll stay away from Pyrex dishes. I also never use extreme temperatures for my borosilicate toys.

Okay, never buying Pyrex from here on out. I was always told they'd crack with a rapid temperature difference... But not an explosive sort of shattering!

I love my pyrex though, you just have to take care of it.

What ScottA said is correct. Though the exact date is subject to some controversy, sometime in the 1980s, the Pyrex brand switched from borosilicate glass to tempered soda lime glass (which is cheaper and easier to work with). Details can be found in this article by Consumer Reports. European "Pyrex", for the record, is still borosilicate construction.

I have had pyrex explode on me in the kitchen. Tim's video was a nice review. Those who haven't seen it, should
