CNBC traveled to Harrodsburg, Kentucky to get a rare look inside Corning’s oldest glass factory where it makes Gorilla Glass for iPhones and a variety of other devices. The factory runs 24/7 and human hands never touch the glass — only air and robots. Take a look inside to see how it's made.
In the middle of bluegrass and bourbon country in Harrodsburg, Kentucky, is Corning's oldest glass factory. It was built in the 1950s to create lenses for glasses and then in the 1980s it transitioned into making LCD glass panels.
But about six months before the first iPhone was released in 2007, Steve Jobs made a call to the CEO of Corning and asked the company to create glass that could withstand scratches and breakage for a new Apple product. Before that, phones were typically covered in plastic. Corning quickly developed Gorilla Glass, and this factory went through a complete transformation.
The same company that developed the glass for the Edison bulb in 1879, is now making the glass that covers 6 billion smartphones, tablets, screens and wearables worldwide for Apple, Samsung, LG, Sony and Huawei and a variety of other manufacturers.
Watch the video to get a rare look inside the factory to see how Gorilla Glass is made.

Yes. Gorilla Glass can still break. But it is more durable and less likely to shatter everywhere.

But why glass is the better solution for a smartphone? Isn't a transparent and scratch resistant PLASTIC surface possible?

It’s so strong that it would not resist to a fall from the pocket. You need to try harder on those gorillas

It's not made from a gorilla???! 😲

I prefer plastic.. ay least it wouldn't break, right? They are now making plastic covers/protectors for your gorila glass screen or a glass cover for your gorila glass screen. '-'

nice video with lots of information. But somehow when watching people with their smartphone many have their smartphone screen cracked and it requires a replacement. Is gorilla glass really the right material for smartphone screens?

corning had this gorilla glass created many years before apple used it -it was just a product sitting around without a purpose
SkylineToTheSeaAndMe (7 days ago)
According to Wikipedia: The product was used until the early 1990s in commercial and industrial applications, including automotive, aviation and pharmaceutical uses, notably in approximately one hundred 1968 Dodge Dart and Plymouth Barracuda racing cars, where minimizing the vehicle's weight was essential. But I know for a fact it was used in optical glass/lens applications where such glass faced potential shock or exposure to shock (such as binoculars). It was used as screen protectors (even in CRTs, and early LCDs, but also in credit card readers/terminals, ATMs, digital gas station pumps, industrial applications, etc.). There were many specialty applications. But the product, chemistry, strength, process technology, and thickness were further refined during the 1990s and 2000s for new applications (like cell phones, tablets, etc.). And there have been competing products/close equivalents since at least the 1970s. These products were developed into AGC Inc. "Dragontrail" and Schott AG "Xensation", (Schott being wholly owned by Carl Zeiss). Leica had a similar product at least since the late 1970s/early 1980s. Many companies who manufactured optical glass for instruments such as telescopes, spotting scopes, cameras, range finders, etc. developed high strength low glare glass similar to Gorilla Glass for these devices or high strength coatings similar to the chemical matrices/formulation of Gorilla Glass. The mirrors in the Hubble Space Telescope had glass similar to Gorilla Glass coating it's refractive surfaces. "Construction of the Perkin-Elmer mirror began in 1979, starting with a blank manufactured by Corning from their ultra-low expansion glass. To keep the mirror's weight to a minimum it consisted of top and bottom plates, each one inch (25 mm) thick, sandwiching a honeycomb lattice." One of these predecessor products was called "Ule Glass" which is/was a high strength low weight glass. https://archive.org/details/DTIC_ADA153783/page/n2

+SkylineToTheSeaAndMe ok "certain devices /instruments " ,that's all i need to know to change my mind ,ty !

It had a purpose in certain devices/instruments, but the flat panel and smart phone industry created a new market for it.

Where i work when they do filming or some fancy pants comes in and they get normal employees to "Act" they do not wear anything that is normally used.

So Gorilla glass was made in 6 month in 1987 just prior the launch of the iPhone? Yeah, ok Lol. Why not add that this tech already existed 40 year prior and was just sitting on a shelf.

And still my gorilla glass phone got shattered 😆😆😆😆
Manav Mohanty (18 days ago)
And how does it break? If Gorilla would have a sane power to deal with humans. Then they would have filed a law suit for defaming them by using their specie's name for versions 1~x.
So which version will be the ultimate Gorilla glass made? Are Gorillas also upgrading themselves?
Note: My 2 phones having Gorilla glaas were shattered. And If Gorilla glass would have been so strong then the sale of screen protector glass would not have been there.
Kent Xenos (18 days ago)
