Gorilla Glass is an unscratchable, unshatterable material used as a protective window for your mobile phone, PMP, or laptop display. It’s in 65 products already, and I can assure you that the very nice man from Corning is not faking it. Your intrepid reporter also gave this several tries with all his blogger strength, and couldn’t make a dent. I was, however, able to scratch the heck out of some polycarbonate.
So yeah, you’ll find this glass in most gadgets with touchscreens or even just your typical screens. Drop it,shoot it, it makes destroying your gadget a much more frustrating task than before. What makes this glass harder then?
When you chemically temper a glass, you immerse it in a salt bath and you stuff larger ions in all the surfaces and put them all under compression.
What’s unique about Gorilla Glass is that because of its inherent composition, it can allow those larger ions to penetrate the surface more deeply to increase the compression tolerance and tolerate deeper scratches.
The compression pushes a flaw back. It’s harder to break from a deeper scratch–Dr. Donnell Walton, Gorilla Glass Engineer
Clearly the use of such material is mandatory given the nature of present devices. Need more proof? Check this out.
