Gorilla Glass, manufactured by Corning, is an alkali-aluminosilicate sheet glass engineered specifically to be thin, light and damage-resistant. Its primary application is portable electronic devices with screens, such as mobile phones, portable media players, and laptop displays. Gorilla Glass's most useful qualities are its strength, scratch resistance and thinness. As of 2010 it was used in about 20 percent of the world's approximately 200 million mobile handsets. Corning says that Gorilla Glass is RF compatible and has outstanding optical clarity, making it suitable for HD and 3D television displays. It has a Vickers hardness of 622–701 kgf/mm2.
Corning experimented with chemically strengthened glass in 1960, as part of an initiative called "Project Muscle". Within a few years it had developed what it named "Chemcor" glass. Corning could find no practical use for the glass at the time and the predecessor of "Gorilla Glass" was never put into mass production, excepting its use in approximately one hundred 1968 Dodge Dart and Plymouth Barracuda race cars, where the reduced weight was key.
