Corning's new glass offers sapphire-strength scratch resistance

Corning's new glass offers sapphire-strength scratch resistance
Apple never delivered on the sapphire glass displays that were expected for the Apple iPhone 6 and Apple iPhone 6 Plus. Churning out millions of sapphire glass screens turned out to be tougher than Apple thought it would be. Still, the experience hasn't deterred Gorilla Glass maker Corning from working on its own product that could compete with sapphire.

Corning's new Project Phire was announced Friday at an investor's conference in New York. The material provides the same protection from drops that Gorilla Glass offers, with the scratch resistance capabilities of sapphire. Corning executive James Clappin reminded those in attendance that sapphire can break when dropped, making this new product a better all around choice for smartphone manufacturers. The Project Phire glass would combine the strengths of both Gorilla Glass and sapphire, which happens to complement the weakness of both materials. Gorilla Glass scratches more easily than sapphire.


Sapphire glass is used on the Kyocera Brigadier and some other handsets, and despite the problems that Apple had with GT Advanced Technologies, it will certainly try again to use the material. After all, it does use sapphire to cover the camera lens and the Touch ID fingerprint scanner on the iPhone. And some Apple Watch models will come with a sapphire screen. The material is the second hardest in the world after diamonds.

In Soviet Russia, Sapphire is used with vodka.

Can't wait for a drop test

I dont know if i can trust corning. My m8's screen is already filled with scratches and here i was thinking gorilla glass was scratch resistant

"scratch resistant" is different from "scratch proof". Try looking at an old phone and see the difference a scratch resistant screen makes.

I installed tempered glass on my note 4. It is way better than GG. It tried to scratch it with knif and it with stand the test. Even the oleofobic coating is great, no oily finger prints

If you can keep your phone away from sand, no scratch apprears

The scratches on my phone are located on the lower right side, which is the part i scroll the most. It was most likely scratched because of my fingernails

What? You dont believe he uses diamond encrusted finger nails polish?

Unless you're Lady Deathstrike, your fingernails shouldn't scratch your screen.

I'd say it's significantly more likely that it's something else you're doing repetitively, like scratching it on a button as you put it in your pocket, than your fingernail (which is about as soft as gypsum) hurting your screen. Ever.

I live 3 miles from a sandy beach, its near impossible to keep my screens scratch free. Thankfully tempered glass screen protectors exist.

Screen protectors are so inexpensive, it would NOT cost any manufacturer any real money to supply say three with the phone I have "Gorilla" protection but have always used screen protectors and when I change my screen protectors and see/ feel the pristine screen, I almost do not want to cover it.. until I see the discarded screen protector and then I know why. re "Apple never delivered on the sapphire glass displays that were expected for the Apple iPhone 6 and Apple iPhone 6 Plus. Churning out millions of sapphire glass screens turned out to be tougher than Apple thought it would be" Vertu USES Sapphire Glass on its phone, sapphire is much more expensive than Gorrila but when you are paying in the $1000 it does not add much to a phone Apple were NOT applying Sapphire Glass in the same sense as Vertu but say Sapphire lite a "cut down" version which most like NOT offer the same protection as say Corning Gorilla glass X We do know Apple did NOT go back to Gorilla glass as on the iPhone5S. There are many complaints by iPhone 6 / 6+ of screen scrathes. Yeah all phomne look good but despite tha why would you still not apply a screen protector/ I HATE seeing any phone which is marked or shattered screen (and those I do see all have one thing in common no screen protector no case) and have dropped my phone a few times despite being ultra carful Good more protection, however screen protectors will not go out of fashion any time soon

Project Phire was part of the Samsung Cheil Industries (now Samsung SDI) joint venture with Corning. They conspired together to combine Gorilla Glass with Samsung's own Infino Brand PC (Polycarbonate) in a composite, that utilizes both material's best traits. Most of all this new screen glass material ends up having even better protection against breakage as with most polycarbonates. The result is an incredibly versatile protective glass, that also has greater flexibility and scratch resistance equivalent to Sapphire Glass! ......and people with devices already, Corning will be making protective screen covers made out of this same material for your phone!!!

"[Sapphire] is the second hardest in the world after diamonds." - Alan F. (PA) Another poorly researched article by PA. Just because you reported on an article by CNET, doesn't mean that you shouldn't conduct your own research. CNET reporters are just as careless as PA's. Sapphire is not the second hardest, and diamonds are not the hardest. In fact, there are two known NATURALLY-OCCURRING materials that are harder, albeit nowhere near as abundant as diamonds.

Your post sounds very stupid, when you don't actually name this hardest material...

Moissanite is harder than sapphire, but diamond is definitely the hardest naturally occurring mineral, graphene and fullerite are harder than diamonds but they're synthetic. I can't find anything about a harder naturally occurring mineral than diamond though, unless Kevin has discovered some harder mineral that he'd probably call Samsungnite or something. Lonsdaleite is THEORETICALLY harder than diamonds, but most naturally occurring cases are below diamond on the hardness scale.

They are probably going to patent Seiko's technology for their watches called saphlex. Seikos hard lex mineral glass is more impact resistant but sapphire is more scratch resistant. So Seiko created a hardlex glass with a sapphire coating that was apparently fantastic according to owners of the watches that had them. However, the sapphire marketing brand and marketing muscle from the Swiss brands pretty much made it obsolete so Seiko slowly phased it out. Maybe Corning is snatching up the patent for phones and will rebrand saphlex as gorill glass 5

Protection against drops.... I think Corning thinks the world is stupid. Gorilla Glass is a gimmick. If you drop a phone, with GG4, it will crack as bad as GG1.

That's not my experience with those I know that have dropped, and those that have dropped and broken are the phones with no real bezel, or where the glass goes to the corners, and yeah I think it will be a while before any glass can handle the shock of hitting the ground with a glass corner.
