I dont think youd have as much of a problem going cold to hot as hot to cold. I was sleeping one night and woke up to a huge smash and screaming while at school. My roommates made cake in a pyrex glass tray and decided they couldnt wait for it to cool down to frost it, so they took it from the oven to the snowy winter outside and within literally seconds it blew up.

They werent very smart girls and this proved it further. I took all of my cookware out of the kitchen the next morning rest assure. less

So, just how strong is Pyrex glass? Well, I put it to the ultimate test! Take a look and see for yourself.

While this is not the "Tell all, be all end of tests" it does give you an idea on how strong Pyrex is. Not only that, it shows you just what happens when a glass toy breaks.

This is my first test for Pyrex, the next test will show what happens when Pyrex goes from the freezer to a pot of boiling water. less
