Pyrex was originally borosilicate glass. Though borosilicates had been produced before, the name Pyrex is widely used as a genericised trademark for the material. Corning spun off its kitchenware division in 1998 as World Kitchen, Inc. However, Corning retained the Pyrex brand name, licensing it to World Kitchen and other companies that produce Pyrex-branded cookware. It has been suggested that Kimax be merged into this article or section. ...

Pyrex kitchen products produced by World Kitchen are no longer made from borosilicate glass, but from soda-lime glass. Their packaging indicates that they must never be used over a flame, on stove tops, under a broiler, or in a toaster oven.[1] Soda-lime glass is the kind of glass which is most widely used for various purposes. ...
Safety issues
Recent reports suggest that due to the change in manufacturing,[1] notwithstanding the claims made for Pyrex, the glassware can shatter violently and unexpectedly, even when used in accordance with manufacturers' instructions.[2] Claims have been made of severe personal injury during these events. The tendency to break into large pieces, rather than shatter like tempered glass, can produce large cutting edges capable of causing serious injury. Some reports have suggested that older Pyrex was not as susceptible to these problems as currently produced Pyrex. It is unknown whether this has anything to do with the recent change in ownership and location of manufacture of the Pyrex brand. It is also a fact that in recent decades the usage of Microwave ovens has increased considerably. Repeated exposure to Microwave might also be a reason of these accidents rather than newer PYREX. This needs to be investigated.
Famous examples of usage Caltech's famous 200-inch telescope mirror at Mount Palomar Observatory was cast by Corning during 1934 – 1936 out of Pyrex, which expands and contracts less than ordinary glass. Modern, commercially built reflector telescopes use Pyrex glass for the primary and secondary mirrors. California Institute of Technology The California Institute of Technology (commonly known as Caltech) is a private, coeducational university located in Pasadena, California, in the United States. ...
