"Pyrex" is a brand name and is manufactured by Corning and is often different glass for different applications.
Most commonly, Pyrex is a "borosilicate" glass. The first borosilicate glass was developed by Otto Schott in Germany and was called Duran. Other brandnames from around the world include Simax, Chinex, Kimble ...
Glasses are known by their flux, a component which lowers the melting temperature of the silica sand which makes the glass, hence the name borosilicate denotes that the flux used is boron.
So, basically, Pyrex is made from silica sand, boron (borax or boric acid), stabilising agents and decolourants as well as some other, minor ingredients.
