For the last decade, consumers have experienced the smartphone revolution which has literally changed the world. Mobile devices have gone from novelty to necessity (did you know that more than one third of consumers worldwide check their phone within five minutes of waking up and that on average they proceed to touch their phone at least 2,617 times a day?*)
With all that our phones mean to us, consumers are demanding more from our mobile phones than ever before. They want devices that are thinner, lighter and aesthetically pleasing – but also more durable to better resist the abuses that come with mobility. And they want scratch resistance and advanced touch capability that keeps the world at their fingertips.
Corning Gorilla Glass has been a key player in the smartphone world from the very beginning. The cover glass that helps protect your phone from damage and enables that incredible touch experience began in a laboratory in upstate New York. Corning's top scientists have performed thousands of hours of tests to understand how and why glass breaks when dropped. And they continue to innovate by finding new ways to strengthen glass to deliver dramatically improved performance against drops on rough surfaces.
How is Gorilla Glass Made?
Corning’s proprietary fusion manufacturing process is at the core of its leadership in glass technology and the cover glass industry. This extraordinarily precise, highly automated draw process produces a thin sheet cover glass with pristine surface quality, outstanding optical clarity and inherent dimensional stability – qualities essential for cover glass for consumer applications.
The process begins when raw materials are blended into a glass composition, which is melted and conditioned. The molten glass is fed into a trough called an “isopipe,” overfilling until the glass flows evenly over both sides. It then rejoins, or fuses, at the bottom, where it is drawn down to form a continuous sheet of flat glass that is so thin it is measured in microns. The glass is untouched by human hands or anything else that could introduce flaws into the surface.
The composition of Corning® Gorilla® Glass enables a deep layer of chemical strengthening through an ion-exchange process where individual glass parts are cut from the “mother sheet” and undergo an ion-exchange process.
