Never happen. That would mean they’d be admitting their current stuff is inferior. 

Everyone agrees that exploding glass is bad.

Interesting article - I actually never knew that Pyrex was no longer borosilicate, despite owning a number of Pyrex items and being an engineer (so you’d think I would have researched better).

Adam, thank you for such an unbiased and thoroughly researched piece!

Do you seriously think that cooking “food” ingredients has an impact on the CTE (coefficient of thermal expansion) of glass?

A Pyrex baking pan once shattered in my hands.

I call bullshit on PYREX and costs. You can buy a Simax Clear Rectangular Glass Roaster Borosilicate Glass 5 Quart from Amazon for $24.99 Prime. A Pyrex Basics 4.8-qt Oblong Baking Dish is $22.16 with Prime. Essentially the same dish for the same price. I would assume the material & manufacturing cost difference is a…

Next time I’m in a thrift shop I’ll be examining glass cookware like a wine connoisseur.  All caps, hmmm?

So, don’t sweat in a hot kitchen, and use something besides pot holders, or anything else that can contain moisture, to remove dishes from the oven. Wooden tongs? Tweezers?

Yeah.... TOTALLY a common sense issue. Everyone should have intimate awareness of the moisture content of all materials in their home at all times. Also, one should be responsible enough to close off one's pores prior to even opening the oven so one does not risk sweating at all.

I bought a set of Snapware containers for my cold lunch salads. I just checked and they are Pyrex. I finished eating my salad and put the empty container into my insulated and lined lunch bag. A minute later the glass dish did it’s explody thing. It broke into the squarish pieces of glass that tempered glass does. Got…

Many companies are learning, why create a great product that lasts for ages, when you can create an inferior product and sell many more during the same time frame for the same *or more* money? Don’t get me started an light bulbs.

About 10 years ago I had a pyrex bake pan explode when I took it out of the oven and the glass went into my finger and I had surgery to remove it.

This article hits close to home. One time I tried to clean my glass smoking pipe by filling a Pyrex measuring cup with water and boiling it over the stove. As I leaned in to inspect the boiling process an hour later, The measuring cup suddenly exploded, shooting shards of glass and a quart of boiling water at my…

So basically new Pyrex utensils are like giant Prince Rupert’s drops waiting for just the right force to act upon them so they can release all the stored energy all over your kitchen — and, with some luck, all over your hands and face.

“A drop of liquid touched the pan so of course it exploded, user error.”

well thats sad.. get a brand that you think means something and then they bastardize it. *sigh*

Actually, I think the reverse is true. Pyrex has changed (and changed their usage instructions, so annoying but not necessarily evil) but people continue to use it the way they did 30-40 years ago.

Several years ago, when making Yorkshire pudding for x-mas dinner, my brother suggested I not use the roasting pan (where the dripping swere) but instead put a Pyrex baking dish in and use that, since it was cleaner. We debated how good of an idea is was, with my brother saying “it’s Pyrex, it’ll be fine” with me…

Heating your wood cutting board will cause the wood to harden and dull your knives quicker.  It also slows down the cooling effect which can lead to soggy crusts or worse, leaving the item in the bacteria danger zone for much longer times.  You can buy a cooling rack.  They work great.
