I’ve read that too. In Europe, Pyrex is licensed to Arc International, which chose to use the original Corning formula. In the US, Pyrex is licensed to World Kitchen which, as you might predict from the name, is committed to a cheaper imported product.

That’s why I always insist on Schott Duran for my thermoglass needs.

I suppose it depends on who is doing the confusing. Since the trademark holder is licensing the name out, it is okay by the law.

I think the trick is to not put it in a situation where it would experience extreme temperature variations in very short periods of time. E.g., a casserole stays warm from the oven to the stovetop, and its surface keeps the dish warm; an eggplant or a couple potatoes rolling around don’t provide the surface coverage for the dish, so the cool air surrounds the entire dish and cools it too quickly. crack.

Wouldn’t this be a trademark violation? After all, preventing consumer confusion is supposed to be the point of trademarks.

“Apparently, the manufacturers say soda lime silicate glass provides better protection against breaking when dropped.
I expect for glassware to break when dropped.
I don’t expect it to turn into 400 °F sharp shrapnel, or I wouldn’t be using it.

We had a Pyrex dish with a casserole in the oven at 350 degrees F. It exploded. In fact, it splintered; when I was trying to clean it up I had a pile of splinters shoving up under my fingernails, bamboo-torture style.

I, too, refuse to buy any Pyrex anymore. It’s all metal, all the time at my house now.

I fancy the not-quite labware from Catamount. The gravy separator/strainer is especially indispensable.

Pyrex may be dead but borosilicate glassware not only survives but thrives.
A search on “borosilicate glassware -pyrex” is all it takes.

You can still buy borosilicate lab glassware. A lot of it comes out of China, these days. If you check eBay, you can also easily get real Pyrex and Kimax stuff.

This is pretty well-known. The real borosilicate is used in things like wood stove doors and telescope mirrors. I think those glass electric cooktops use it as well, and possibly some oven doors, but Pyrex stopped being Pyrex a long time ago.

fwiw, don’t put it under the broiler, either. that’s how i ended up with molten, exploding tofu.

My mother once exploded one of our pyrex casserole dishes. She put it right under the broiler (with a very nice piece of fish).

She went to pull it out of the oven a few minutes later and BOOM! Tiny bits of glass everywhere.

It did say “no stovetop, no broiler” on the dish itself, though.

I believe that in Europe, Pyrex objects are still made out of borosilicate.

those of us who make our own backyard wood fired pizza oven covet the old pyrex for its ability to be used in very very hot oven, as a substance to have light shining thru it it illuminate the oven.

I made jello a few years back. Poured the boiling red mixture into a pyrex container (I was pretty sure that what “Pyrex” was for?) and it exploded. I’m still periodically finding sticky red goo behind cabinets or behind things hanging on my kitchen wall. I found glass 15 feet away. Haven’t bought another pyrex product since.

Not sure this really qualifies as news, this has been fairly well known for a couple of decades now… If my memory serves, Consumer Reports did a test a few years back to see how the new stuff did, and it did better than other brands in heat exchange but nothing like the borosilicate glass.
