How Gorilla Glass Works

Gorillas in the Glass

The ion exchange process isn't new and Corning's Gorilla Glass isn't the only chemically strengthened glass on the market. But Corning has demonstrated the strength of its glass in venues like the Consumer Electronics Show where the company invited people to test come up and see how much pressure it would take to break a piece of its glass. Untreated glass would break relatively easily. Standard chemically strengthened glass would put up more resistance but would also break given enough pressure. Gorilla Glass was much more resistant to damage.

How does Gorilla Glass get into products? Corning partners with manufacturers and provides Gorilla Glass as part of the product's manufacturing process. The average consumer can't go out and buy a sheet of Gorilla Glass to fit on top of an existing device. In that sense, Corning is an original equipment manufacturer (OEM). The finished product will contain Corning's glass but the finished product will have another company's brand on it.

Corning isn't allowed to reveal all the products that use its Gorilla Glass. But among the products the company has announced are the Sony BRAVIA line of television sets, the Samsung Galaxy Tab tablet device and the Dell Streak. While smartphone manufacturers may look into Gorilla Glass to help their products resist the wear and tear that comes with moving a portable device around, television manufacturers are considering it to make their products more durable.

Because Corning's fusion draw process creates thin sheets of glass that don't inhibit applications like capacitance touch screens, you may see a lot more smartphones and tablets that include Gorilla Glass in their construction. Corning's manufacturing process and the explosion in popularity of portable devices may be timed just right to propel the company to success.
