  • In the middle of bluegrass and bourbon country in

  • Harrodsburg, Kentucky is Corning's oldest glass

  • factory. This facility was built for ophthalmic

  • glass pressing in the early 1950s.

  • And then in the 1980s, we transitioned into the

  • fusion forming process to make LCD glass. That

  • grew into an enormous business for us within Corning.

  • 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.

  • We leverage the fusion forming technology to make

  • Gorilla Glass and to make the first composition

  • of Gorilla Glass here in Harrodsburg. Since 2007,

  • I could say that the Harrodsburg plant has

  • undergone a number of innovations to support all

  • of the new Gorilla Glasses as they transition to

  • stronger and more scratch resistant and more durable glass.

  • 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. We got a rare look

  • inside Corning's flagship Gorilla Glass factory

  • to find out how it's made.

  • Robots and massive machines are continuously

  • making glass 24/7 here. It starts with a mix

  • materials that are sourced from all over the world.

  • Here we are in the mix house. This is really where

  • the heart and the start of the Gorilla Glass

  • composition begins.

  • Some people may think the glass is just sand but

  • it really isn't. There's a lot of complex science

  • that goes into Gorilla Glass specifically.

  • It is extremely important that we have a strong

  • and robust recipe. So as you think about how you

  • make your cake at home similar to that we have

  • fine tuned and evolved the process for making

  • glass over decades. What you can see in the

  • facility are screw feeders and feeding systems

  • that will take that material and transition it

  • into a large bowl where it will be mixed so that

  • we ensure that the mixture is homogeneous and can

  • create the best glass possible.

  • One bag, as you see here, once it's filled will

  • actually turn into thousands of sheets of Gorilla

  • Glass. The raw material then travels up seven

  • stories to the top of the factory. Where it

  • enters a giant oven turned up to more than 1,800

  • degrees Fahrenheit. Corning did not allow us to

  • film the oven for fear that competitors would

  • figure out its secret sauce and take a chunk of

  • its $11.4 billion in sales in 2018. But it was an

  • impressive giant machine that melts the raw

  • material to hot molten glass over the course of

  • days. The lava-like glass then flows down several

  • stories while it cools and strengthens in a

  • process called fusion forming. So to describe our

  • fusion forming process, if you imagine a trough

  • and the glass comes into the top of that trough

  • and then flows over the edges of the trough down

  • to the point where it fuses together.

  • It's really fusing together in air and nothing

  • touches that pristine surface so both sides of

  • the glass are pristine as it transitions down

  • multiple stories to the bottom of our process

  • where it's then scored and separated into

  • discrete sheets. Fusion forming process is

  • capable of making thicknesses of glass over two

  • millimeters down to 100 microns or dot one

  • millimeter, which is just larger than the size of a strand of hair.

  • The glass comes out of the fusion process in

  • sheets that are cut as big as 9 feet by 10 feet.

  • Only robots touch the glass throughout the

  • process. And sometimes the robots make mistakes.

  • So as the glass transitions to this final step

  • before it gets shipped and packed realize that

  • the glass has never been touched by human hands.

  • When it gets to this final step, we laminate the

  • glass to protect it both for shipping and to

  • allow our customers to handle the glass as they

  • pull the sheets out of the crates. The sheets are

  • then transitioned into crates where they're

  • further packed and ensured that they're in

  • pristine condition as they ship.

  • Early on in fusion glass development there were

  • some manual steps but we found that those manual

  • steps could impose safety concerns. And so the

  • robots were really developed to enhance our

  • manufacturing process and to eliminate the safety

  • involved in handling glass.

  • We can create glass from extremely thin to 100

  • microns to two millimeters thick.

  • Depending on the thickness of glass, it really

  • determines how many sheets of glass we pack in a crate.

  • But crates in general can have hundreds of sheets

  • within one crate. We really have limited breakage.

  • Once it's loaded into crates the glass is then

  • shipped off for finishing, which is done all over

  • the world depending on the preference of the

  • device manufacturer. Gorilla Glass is one of the

  • toughest glasses out there. And what makes it

  • tough is not only what you see here because it

  • actually hasn't obtained all of its strength at

  • this point. After it's packed and shipped it goes

  • through a chemical strengthening process called

  • an ion exchange process. The composition that

  • we've set up allows us to then take a finished

  • sheet of glass put it into a bath of hot salt and

  • in that bath of hot salt sodium ions are

  • exchanged for a larger potassium ions in the glass.

  • And if you imagine those larger potassium ions

  • pack into that glass causing a much tighter and

  • stronger compressive area on the glass. And

  • that's really what gives the glass its strength.

  • Corning employs 400 people at this factory, many

  • of whom are focused on quality control and

  • research as device manufacturers demand thinner and sleeker phones.

  • Corning is constantly having to update and improve

  • Gorilla Glass to try to keep this from happening.

  • What makes Gorilla Glass so strong is the unique

  • composition and glass science behind the glass.

  • That allows us to create this compressive layer

  • that, when it is ion exchanged, creates really a

  • layer of armor and an extra strength that other

  • glasses are not capable of doing.
