Corelle still uses the same really excellent formula they've always used, though. I have a mixed set of new and old Corelle dishes (<1 yr old and >10 years old), and I can't tell the new ones from the old ones.

This is certainly not my understanding. After production left USA quality is worse. Breaks more often and when it shatters, it doesn’t just break apart. It’s like a kinetic blast sending forth hair and bigger sized razor sharp glass shards in a surprisingly wide radius. It’s like a mutually assured destruction event and will require heavy clean up and you still might end up with glass in your feet and eyes.

I remember reading the Amazon reviews and the amount of 1 star stories about how a plate landed them in the ER was concerning.

I bought some vintage Corelle at a private sale and it seems different to me at least but maybe I am buying the wrong contemporary stuff.

I wonder if some of the bad Amazon experiences are due to counterfeit/fakes, and/or the product lines that are made in china? Their products vary in materials and country of manufacture. The ones I like are made of Vitrelle, come directly from Corelle, and it's one of the product lines they still make in New York: https://www.corelle.com/product/winter-frost-white-78-piece-...

I think they're all (even the vintage ones) subject to risk of shattering into pointy shards if they break, though. They're not magic. :)

Corelle plates have always been that way, I think. I was raised using them, and I still buy them now that I have children of my own.

For me, they're 100% shatterproof until they're not. You can drop them over and over again, and never notice any visible change. But then when they finally do shatter, it's almost like an explosion.

I think this is because they're built from a pressurized metal/glass layered composite. Very sturdy until enough internal damage builds up.

More or less matches my experience, including having been raised eating on Corelle dishes. They'll take drop after drop and then suddenly the last one leaves a giant mess to sweep up. Every time.

I have discovered that if you leave a Corelle plate outside during the winter, in the spring it will be broken into little bitty pieces. It can't handle the freeze and thaw cycles which surprised me.

I assume you’d didn’t leave a plate outside for an entire season by accident? You’re running experiments on your dishes?

That’s pretty funny (and awesome)

A little bit of on purpose, a little bit of not caring. I had it underneath a small plant pot and just left it out there. I found it interesting that it can handle hot thermal stress (expansion) but not cold (contraction).

Corelle is owned by the same conglomerate as Instant and Pyrex, it seems.
