Corningware Glass Stovetop Cookware
Regular glass cookware, even Pyrex, is not really suitable for stovetop cooking. In the mid 1950s Corning Glass Works found a way to solidify glass (which is normally a supercooled liquid) into a ceramic-like form, and in 1958 released CorningWare.   Photo by Splarka contributed to the public domain.

General & History

The only company I've heard of that has developed glass cookware suitable for the stovetop is Corning Glass Works. They had two lines, CorningWare (opaque) and Visions (transparent). They discontinued production in the late 1990s but some production has been revived in 2009.

The brands now belong to World Kitchen, and they are selling a limited line of both products from their Web store. Most of the World Kitchen products under the CorningWare brand are not glass but regular ceramic products not usable on the stovetop.

CorningWare Pyroceram
CorningWare Shown here are the Pyrocerm items currently sold by World Kitchen on their Web site. The Pyroceram product has a very good reputation and is legendary for being able to be moved directly from freezer to stovetop without breaking. Because it lasts forever repeat customers have been a problem. The lids are Pyrex, another famous brand name now owned by World Kitchen.   Photo © Source.

Visions Cookware This cookware has been popular, but is more fragile than Pyroceram, though people have admitted to abusing it fairly severely without problems. The downside is that there have been scattered reports of Visions cookware simply exploding into tiny fragments when not under particularly severe stress. High stress testing has been done without being able to duplicate this failure. Shown in the photo are items currently sold by World Kitchen from their Web site. The lids are Pyrex, another famous brand name now owned by World Kitchen.   Photo © Source.
