Are you talking about Kitchen grade Pyrex (Tempered Soda Lime Glass) or Lab grade Pyrex (borosilicate glass)?
Lab grade contains more metals such as boron, sodium, and aluminum making lab grade glassware better conductors of heat.
pyrex: a glass pipe fog: your drug of choice
Pyrex glass is designed to withstand sudden & drastic TEMPERATURE changes. Most glass will shatter with sudden temperature changes. Pyrex is not bulletproof. Most transparent bulletproof material (glass) is composed of several layers of plastic & glass sandwiched together. The plastic holds the glass together, while the glass absorbs a bullet's impact.
Only if it is Pyrex glass.

Anchor hocking is a separate 2nd largest glassware company.
