Only in the US where Pyrex is made by World Kitchen. In Europe, Arc Internationl still uses borosilicate for Pyrex-brand glass. Also, FWIW, a popular US glass bakeware manufacturer claims tempered soda-lime glass is stronger while still as heat resistant as borosilicate:
That's really funny, because a glass baking form made by Anchor shattered in my oven recently, spraying the whole oven with glass shards, ruining my food, and making it a huge pain to clean up.
So... as heat resistant as pyrex? Not in my experience.
