Pyrex: no longer oven-safe
Three Years Later: Pyrex Dishes Still Go Boom
http://en.wikipedia.org/wiki/Borosilicate_glass
After Corning Glass Works introduced Pyrex in 1915, it became a synonym for borosilicate glass in the English-speaking world (however, since 1998 Pyrex kitchen brand is no longer made of borosilicate but of soda-lime glass[2]).

Soda-lime glass, also called soda-lime-silica glass, is the most prevalent type of glass, used for windowpanes, and glass containers (bottles and jars) for beverages, food, and some commodity items. Also Pyrex brand kitchen glassware manufactured since 1998 (when the brand was spun off under World Kitchen) is made of soda-lime glass[1] (previously, it was made of better quality, thermal shock resistant borosilicate glass).
