I have been reading about this today....
It is very alarming! http://www.consumeraffairs.com/homeowners/pyrex.html Anyone here have an experience? I've used glass Corning cookware for most of my life. I had one explode upNorth about 10 yrs ago. But no others. Granted I don't bake in ovens much anymore, but now I wonder. Snopes.com says only the newer Pyrex is affected, not the older versions. A Chinese company is making a different form of this glass and using the Pyrex logo and name. So do be careful if you use glass bakeware. There are reports of this glass just exploding sitting at room temperatures as well as sitting in cupboards!

I've not heard about the pyrex.
I still have some pyrex from years and years ago. The work they've done over the years is amazing and never had any problems. I'm talking 25/30 year old pyrex. I've heard about drinking glasses bought from the dollar stores here exploding/shattering for no particular reason. I've also heard about glass cooktops exploding. (and even oven doors). |

Great excuse to not cook!
I haven't ever heard of this but it's interesting. I have two or three older Pyrex dishes and two Pyrex measuring cups. I use the glass dishes mostly to store things in the refrigerator in. Sometimes use them in the microwave.

Evidently this problem has escalated recently. The old Pyrex from years ago was a borosilicate glass.
The new Chinese Pyrex (WalMart is a main outlet for it) is soda lime glass...which is less heat tolerant or temperature safe. What is alarming is that the reports, and I only read a smattering of them since there are SO MANY.... report explosions with new product at room temps and some just sitting on the counter! Snopes.com-- http://www.snopes.com/food/warnings/pyrex.asp I've always used glass, Pyrex and Visions because there they are not metal, and supposedly safer for less contamination of food. Now I don't know what to think anymore! All of mine are OLD as well, like yours Lara.

We also used Pyrex and Kynex glassware in the labs when I was in college, in chemistry. Nothing ever exploded there, but then the glass was thinner than a baking dish. We used to expose that glassware to all sorts of temperature changes too. I would call the use by most of the students rather "abusive" in fact.
I guess NOTHING is safe anymore!

I checked some of mine.
Strangely enough the newest Pyrex I bought says made in the USA. It's a see-through glass pie dish. Another little casserole dish with a glass lid is one which must be about 20 years old and has a star like symbol and the name Corning P4 but says "cerammed" in Australia. I did some reading around briefly after you posted and it sounds as if it's the impurities in the product that can cause it to explode or shatter. Not very good is it?! Those old vision saucepan sets were great. They didn't seal very well I thought but I really liked using them, thinking they were the healthy alternative at the time to what we aussies call Aluminium. |

One article mentions that the "inferior" Pyrex has a faint greenish tinge where the glass is the thickest.
Evidently the Chinese owned Pyrex is made in USA...this makes it very difficult to identify as "different". Corning sold the patent. One article also mentions micro cracks that may develop which then absorb water, and then burst when heated. But that does not explain the bowls that burst sitting at room temp -- the water bowls for pets and the one that burst sitting in a cupboard! I've used Visions on the stove now for almost 20 yrs...the only one that broke was the one my husband dropped a heavy thing into by accident, and it broke in half. But he knows a gal at work who claimed her Visions pot blew up on the stove cooking. I typically use mine for stews, soups, and pasta. I'll pour out the hot liquid and leave on the gas stove burner to cool off. I don't move them to a counter, I leave them on the hot burner so that both can cool down together. When I stack them for storage I put bubble wrap between them. But I don't put bubble wrap in my Corelle bowls or smaller visions glass dishes when stacked which we use to nuke the veggies in the microwave. Those are really handy and never exploded on me. 2 minutes in the wave, doesn't seem stressful enough? Frozen veggies heated up and nothing explodes.
