So it would be worth it to seek out old Pyrex at flea markets?

The old stuff is so much better quality. I have beat mine up, put it straight onto counters, put into cold water, gone from fridge to oven. No problems.

Worth buying the old stuff.

Idk if its because of the coronavirus bulllshit everywhere but I laughed my fricking arse off at this thread.

The absolute state of Pyrex, lad.

That's what happens when proto mater is used. Most unstable.

You likely had a pyrex dish instead of Pyrex. Corning used to make Pyrex out of borosilcate glass which has a VERY high tolerance for thermal shock but today pyrex is made from soda-lime glass with a much lower tolerance for thermal shock. What you describe would be VERY rare if it was borosilcate glass. With quality borosilcate glass you would have to do something like direct from the oven to an ice bath to cause an explosion.

ETA I should have explained when Corning sold the Pyrex name the company that owns the name moved all production to China and went from boro to soda lime glass and the P in Pyrex is no longer capitalized.

I have seen the difference in thermal shock in boro and soda-lime glass many times. My wife's hobby is hot glass work, when something goes wrong with something she is working on using soda lime glass she just sticks the mandrel with the glass on it in water and it explodes off the mandrel even when boro is almost straight of the torch and incandescing half the time it won't explode when it hits the water, sometimes it will crack but it won't shatter into a bunch of pieces.

Some of us check for the made in USA on the bottom of Pyrex and buy accordingly.
