I ordered some new lids from World Kitchen for our 5-cup Pyrexware bowls and they arrived with a Use and Care leaflet for CorningWare Pop-Ins. The leaflet was dated 1998 and lists the manufacturer as Corning Consumer Products.
The instructions state that CorningWare Pyroceram is safe for use under the broiler and in both microwave and conventional ovens. It also warrants the Pyroceram components for 10 years.
Contrast this with the Use and Care instructions for "CorningWare" stoneware, which clearly warns you NOT to put it under the broiler. The warranty has been reduced to ONE year because if you use stoneware as freezer-to-oven-to-tableware, it WILL fail, most likely within the old 10-year warranty period.
It took a mere 8 years for World Kitchen to utterly destroy an American icon. Heartbreaking.
