This just happened to us, thank god there were no injuries. People need to be aware of this!!!
Glass kitchenware is also tempered. I inadvertently turned on the wrong stove burner, and heated the center of an old Corelle dish to red hot. I saw the error and removed it, and allowed it to cool slowly. No apparent change. But several days later, I washed it, scrubbing it hard to remove baked on grease, with a Scotchbrite pad. I rinsed it and left it to dry in the dish holder.
Your tester would be safer wearing a simple face shield with the safety glasses .
I think this needs to be treated as a case of false advertising.
The name Pyrex tells me in the laboratory that I am holding a piece of borosilicate glass. If I pick up a piece of cookware that says Pyrex I shouldn't have to ask it's age or it's composition.
I need to go hand write 500 word letter on this topic and send it around. So should the rest of you. There's a TED talk about writing letters.
In France, we still make Pyrex with borosilicate glass. It has a slight blue tint to it, but apparently some countries put a blue tint to their inferior soda lime glass. The French products say "PYREX Made In France". The French products are rated for -40 deg F to 572 deg F (-40 to 300 Celsius). Even with the French Pyrex, you can't put them on a burner or open flame. A 2 Qt bowl here costs about $10, so I don't know why they say that borolisicate is so expensive. We don't bake sand here.
The whole point of Pyrex was that it was boro-silicate glass and therefore more resistant to thermal shock.
My baking dish exploded xmas eve yesterday. I had just pulled a tray of cornbread from the oven and then set it on my cool granite counter and it exploded quite violently similar to this video. I see the cause was partly my fault for doing this but I am going to stop using glass bake wear completely. Why use glass if even there is a remote possibility of an explosion happening at only 375 degrees? All metal pans lined with parchment from now on. Be warned.
Old Pyrex is better then new because like all stuff nowadays they charge more for less product. You get junk for the old price but marked up.
soda lime glass can resist temperature difference in less than 55C (99F), borosilicate can tolerate temperature difference within 183C (330F).
Last night, local station KNXV covered this story; their news anchor had a humorous (and very appropriate) tongue slip:
"BREAKware."
so they're not shattering from the actual heat, but instead if it's placed on a wet or extremely cool surface after being exposed to heat, yes?
Severed the tendons on both feet, WTF.
This is why I only use cast iron!
i had a pyrex pan that shattered in my oven just this morning. and i did nothing out of the ordinary with it, no sudden temperature changes, oven was pre-heated, etc. after about 15 mins in the oven i heard a loud bang and sounds of glass crumbling and falling
This just happened to us on Christmas!! It was a brand new 13x9 baking dish and had already been cooking for over 45 minutes! It EXPLODED, not just cracked or shattered. It was a brand new Pyrex gift for Christmas.
This is why I stopped bothering with cheap US based Pyrex years ago. Now I only buy OXO or Simax which is borosilicate.
I have some Pyrex-branded baking dishes and pot lids bought in Europe in early 2000s. They have a blue tint suggesting fake glass. The bowl of a convection oven branded ARC France has the same tint. Commenter Overcat below said that blue glass actually may be borosilicate. Whom to believe?
On saturday ( today is tuesday) a pyrex dish randomly exploded while my grandma took filet minion out of the oven. It didn't hit anything it juts exploded so be aware when you use pyrex
my just has just exploded all over my kitchen. It was sitting on a shelf, not being used. Why?
I just had a pyrex glass casserole dish explode today in my kitchen. I took it out of the oven and put it on top so it could cool down and it exploded!
