My impression is that Chemcor hadn't been completely shelved after its invention, just that it hadn't found any hugely profitable uses. I'm reasonably sure I've seen the brand name before. http://www.corning.com/gorillaglass/gorilla_timeline.aspx http://www.corning.com/gorillaglass/gorilla_timeline.aspx says "1965: Chemcor glass was used in many commercial and industrial products until the 1990’s. Variants of Chemcor continue to be used in ophthalmic and pharmaceutical products." I found http://www.springerlink.com/content/w1142mnnt5u61410/ http://www.springerlink.com/content/w1142mnnt5u61410/ which is a journal article (translated from Russian) from 1982, discussing the ion-exchange annealing process used to strengthen Chemcor and similar glasses. I also found an interesting Time magazine article from 1962 about Corning, which opens with a paragraph about Chemcor, and later mentions "[Corning's] new Chemcor has a wide range of potential industrial uses as a cheap, strong substitute for plastic, but has so far been used only for a virtually unbreakable tableware called Centura." Apparently Centura was not microwave-safe, and was discontinued in the late 70s: http://www.corellecorner.com/centura-dinnerware-tableware-pattern-profiles.html http://www.corellecorner.com/centura-dinnerware-tableware-pa...
