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.

    Need to figure out a way to make a boat hull out of this stuff. Would slowly 'racking' the two molten layers back and forth, so that the two layers fuse at some degrees off the vertical angle giving a 'weave' effect offer any improved results?

    @0:28 Correction: That story about Steve Job calling Corning about GG1 is the most common you will hear. Corning had already developed GG1 but they were not using it for customer devices. Jobs went to them to get a type of tampered glass for his new IPhone and Corning told him about Gorilla Glass aka GG1. Impressed, he ordered GG1 for his new IPhone which later came out in 2006-2007.

      If you are talking about a foldable phone with a (ONE) foldable screen (not TWO screens side-by-side), that "corner" is very, very far away. Had it been easy to manufacture, Samsung or LG would have already launched it and Apple would have already copied it an called it it's own "innovation".
