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.
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.

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.
