What kind of glass does Pyrex use?

borosilicate glass Pyrex bowls were originally made of something called borosilicate glass, which is very resistant to thermal shock. Currently, Pyrex is made of soda-lime glass, presumably as a cost-cutting measure, as soda-lime glass is very inexpensive.

Is Pyrex better than borosilicate?

Pyrex pieces used to be made of borosilicate glass, which is more resistant to breakage when subjected to extreme shifts in temperature. Although tempered glass can better withstand thermal shock than regular soda-lime glass can, its not as resilient to such stress as borosilicate.
