In the tech equivalent of a turkey dissing Thanksgiving dinners, Corning SVP Tony Tripeny has criticized sapphire as a material for protecting phone screens, coming up with a whole list of claimed drawbacks, reports CNET.
Sapphire is far more resistant to scratches than Gorilla Glass, but Corning argue that it is more likely to be smashed.
Apple is expected to switch to a sapphire coating for the iPhone 6, manufacturing the material at the plant it jointly operates with GTAT in Arizona. While the material is indeed currently much more expensive than glass, it has been suggested that the costs could be substantially reduced with new production techniques.
