Glass is only useful when baking something heavy that a sheet can't hold like a lasagna

is it based on how much you use it or just time, because mine is pretty old

@crisp@poa.st @s8n@posting.lolicon.rocks @lonelyllama@kiwifarms.cc _Consumer_ PYREX(TM) shifted to soda-lime glass some time ago, per Wikipedia in the 1980s, but Corning knows glass and it is my understanding they properly tempered it. They spun off this unit in 1998, and the new company that covers the US, South America and Asia stopped doing it properly, and there are lots of reports including 66 official ones to the US Consumer Product Safety Commission in the next ten years of it shattering when the consumers thought it shouldn't, which the commission didn't agree with.
All I can say about the latter is that my grandmother and mother were heavy users of Corning cookware procured before the 1980s and it _never_ shattered due to thermal issues, although they were smart enough not to overly stress it. And I only use this older stuff, although I'm not absolutley sure about the two measuring cups I use, but they're definitely from the pre-spinoff days.

@s8n@posting.lolicon.rocks @lonelyllama@kiwifarms.cc I should be okay, but I am planning on making lasagna soon and would suck if this happened

@ThatWouldBeTelling@poa.st @crisp@poa.st @lonelyllama@kiwifarms.cc @s8n@posting.lolicon.rocks I've always considered the "new Pyrex is unsafe" thing to be one of those "I am a more discriminate consumer than thou" redditor things.
The change was likely made for safety reasons, real borosilocate is brittle (even for glass) and breaks into large, razor sharp chunks per my experience with lab quality glass. Soda lime can't handle freezer-to-500° oven as well but it also won't shatter into a hundred knives in a small drop.
It's not like you can't just consoom your way to borosilocate baking dishes via google anyways.

@ThatWouldBeTelling@poa.st @crisp@poa.st @lonelyllama@kiwifarms.cc @s8n@posting.lolicon.rocks Like I said, it's still cheap and available, it's just that one brand moved away from it.
