Corning Gorilla Glass vs. Sapphire

As Corning® Gorilla® Glass surpasses 1.5 billion devices sold worldwide, it’s hard not to reflect on what’s made the product the cover glass of choice for the consumer electronics industry.

The profound influence Gorilla Glass has had on consumer electronics has led to dramatic improvements in screen durability, image clarity, and touch performance with a material that is both thin and tough.

Recently, speculation has arisen that manufactured sapphire crystal might become an alternative to Corning’s Gorilla Glass, but according to James R. Steiner, senior vice president and general manager of Corning’s Specialty Materials segment, Corning’s not too worried:

"Sapphire's performance as a cover for high-end watches probably leads to the current speculation. But those covers are much smaller than a mobile phone and are two to three times thicker than Gorilla Glass. In one of our commonly accepted strength tests, sapphire breaks more easily than Gorilla Glass after the same simulated use. Additionally, sapphire’s cost and environmental hit are huge issues."

Furthermore, Corning isn’t standing still. We’ve already announced three versions since 2007 and more improvements are on the horizon.
