Pyrex is also known as borosilicate glass.
It consists primarily of Silica and boron oxide.
According to Wikipedia, typical borosilicate glass is composed of:
70% silica (silicone dioxide SiO2), 10% boron oxide, 8% sodium oxide, 8% potassium oxide, and 1% calcium oxide (lime).
Wikipedia does note that some kitchenware glass marketed as Pyrex is actually soda lime glass.
