Corning sold off all their brands in 1991 to a brand marketing company (Corelle Brands) that then contracted with other manufacturers to produce them. This applies to Corelle, Corning Ware, and Pyrex. The same company scooped up Chicago Cutlery and some others, too. They reformulated and redesigned products at will. Don't assume modern Pyrex products are ovenproof, for example. They are no longer made of borosilicate glass.

Sounds like a conspiracy hoax (to make them planned obsolesent) to me.
