But which type of Pyrex are people talking about? ‘Pyrex’ or ‘PYREX’
It’s two different companies.
After the company split the stuff made for America was no longer borosilicate and made from a much cheaper, weaker, less heat resistant type of glass.
The European Pyrex branch stuck with borosilicate.
I’ve had most of my Pyrex for over twenty years. It’s incredibly durable. Unless you drop it from a height
So I guess you need to check which type of Pyrex/PYREX yours is
Edit the weaker glass is called soda-lime glass.
