Corning, a company that supplies Apple and many other device vendors with its chemically strengthened glass, on Thursday announced the fourth-generation Gorilla Glass which it says has been designed to be up to two times tougher against drops on rough surfaces than “any competitive cover glass design now in the market.”

The announcement comes at an interesting time for Apple in light of its failed experiment with sapphire maker GT Advanced Technology which led to GT’s unexpected bankruptcy and an unused $1 billion manufacturing facility in Mesa, Arizona.

Although the California firm planned on protecting the 4.7 and 5.5-inch screens on the latest iPhone 6 devices with ultra-thin sheets of sapphire, the plan was scrapped following GT’s failed attempts to ramp up production and meet Apple’s exacting standards in terms of volume and yields.

Corning claims that the Gorilla Glass 4 provides at least two times improved damage resistance over competitive aluminosilicate glass, “as measured by retained strength after damage events,” resulting in improved mechanical durability of the glass to in-field damage events, such as drops.

The material apparently survives up to 80 percent of the time, as opposed to soda-lime glass found in today’s commercial devices, which breaks nearly 100 percent of the time.

Based on an internal analysis of hundreds of broken devices, Corning found that damage caused by sharp contact accounted for more than 70 percent of field failures. It’s the primary reason that mobile devices break, Corning concluded.

The new Gorilla Glass 4 went through a barrage of new tests that simulate real-world break events, like dropping devices face down from one meter.

And here’s a testing video.

The glass is manufactured using Corning’s proprietary fusion draw process which maintains the thinness, durability and optical clarity while “dramatically improving” drop performance.

Since its launch in 2007, Gorilla Glass has been featured in more than 3 billion devices, among them in all iPhone generations.

    Wow, it looked so obvious that the woman dropped the phone on purpose. xD

      She’s hot though 😉

    Damn it, Anna! WILL YOU STOP DROPPING YOUR PHONE! Who, in the right mind, would ever gift her something with a screen? Anna, I think we should talk…

        I lire where this is going.

    Every year, we say, “This will be on next years iPhone!” … And it never does lmao.

    • Apple doesn’t like to admit it but a quite a few models used Gorilla glass.

      • Jeffrey

        Actually all of them did… Lol.

      • I figured it did, just couldn’t verify if the 6/6 Plus used it yet. It’s no longer listed on corning site because Apple doesn’t want it their.

      • Jeffrey

        Yeah they use the glass but they simply changed the name of the glass to ‘Ion strengthened glass’ :P.

        I thought I read in the Steve Jobs Biography that he had something to do with Gorilla Glass. I can’t remember exactly, but I remember him having something to do with it.

    Will it blend?

  • TechAlex

    Are the gorilas getting some compensation for using their pics?

    • Yes they are paid in Samsung products and bananas since they are worth about the same.

  • yungcinnabun

    Apple never used the newest latest technology so this is pointless
