Inside Corning's Gorilla Glass Factory

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.

    194 countries use metric. 1 country uses a cave man system. Still, in this video, that is mostly watched by people from those 194 countries, you are using this system, that nobody except the people from 1 country understands. Makes sense. Very American. Nice video, but thumbs down for not using the SI units.

      According to Wikipedia: The product was used until the early 1990s in commercial and industrial applications, including automotive, aviation and pharmaceutical uses,[6] 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.
