Why does a pyrex glass not crack when boiling hot tea is poured into it?

Pyrex glass is made with borosilicate material, which has a higher resistance to thermal shock compared to regular glass. This allows Pyrex to withstand sudden temperature changes, like pouring boiling hot tea into it, without cracking. Additionally, the design and manufacturing process of Pyrex glassware contribute to its durability.
