The evolution of Corning’s Gorilla Glass

In 1952 a scientist at Corning placed a piece of photosensitive glass in a furnace for testing. The furnace was set to 900 degrees Celsius; expecting a melted mess the scientist found what appeared to be an opaque sheet of material rather than that of a melted blob of nothingness. naturally intrigued the scientist then proceeded to take the sample out of the furnace, he struggled and actually dropped the sample onto the floor. What he found was rather extraordinary, instead of shattering into smithereens – the glass actually bounced.

The scientist had actually created a glass-ceramic hybrid. He later found out that this glass was a lot stronger than the glass of his era, it was also lighter than aluminium and as hard as steel. this new discovery found its way into various products; from missiles to microwaves and would later be developed in to the household staple name Corningware.

Corning worked on trying to strengthen the glass through the 60’s, through that study they discovered that if they placed the new glass in a potassium bath it would strengthen the glass quite significantly through an ion exchange.

What is an ion exchange I hear you say:

Ion exchange is a chemical strengthening process where large ions are “stuffed” into the glass surface, creating a state of compression. Gorilla Glass is specially designed to maximize this behaviour. The glass is placed in a hot bath of molten salt at a temperature of approximately 400°C. Smaller sodium ions leave the glass, and larger potassium ions from the salt bath replace them. These larger ions take up more room and are pressed together when the glass cools, producing a layer of compressive stress on the surface of the glass. Gorilla Glass’s special composition enables the potassium ions to diffuse far into the surface, creating high compressive stress deep into the glass. This layer of compression creates a surface that is more resistant to damage from everyday use.

So they basically forced out all of the smaller ions and replaced them with larger ions, these compressed when cooled to create a much tougher glass. This project was originally named “Chemcor” and the intent was for the product to be used universally. However it never took off commercially, companies just didn’t want to pay for something that they didn’t really need. The laminate glass that was designed in the 30’s was still doing the job, so why change. Corning got their new compound out to very few manufacturers/companies and were simply not making enough money; so the idea was scrapped.

In 2006 a man named Steve Jobs was testing a new prototype called the iPhone. Steve and his crew wanted to create a Smartphone that defied all odds. Jobs realised that the plastic screens used in 2006 were simply not strong enough to withstand the daily challenges that they were coming up against, keys and coins being the biggest culprits for example. Timing played a huge factor in the process of Apple obtaining Gorilla Glass for their Smartphones. Jobs contacted Corning and set them the task of finding a suitable glass module that would work with his new concept, what Jobs didn’t know that a full year prior to his request Corning had already began exploring that concept.

Apple became enchanted with the idea of using this type of glass. They gave Corning their desired specifications. Apple required a glass just 1.3mm thick, this was well below half of what Corning had ever produced with Chemcor. Corning naturally began to feel pressurized as they failed to tell Apple that they had never mass produced products like this before. Corning took the risk and agreed to Jobs’ request, they then set their scientists the task of producing a new glass for Apple. They named it Project Gorilla Glass.

Now the world’s leading tech manufacturers are using Corning’s Gorilla Glass: Apple, Samsung, Sony, HTC, Nokia, Motorola, Acer & Dell just to name a few. This really does paint a picture as to how quickly they have evolved in such a short amount of time.

Corning are always seeking to improve their designs when possible. Many of you will already know that a lot of todays Smartphones/Tablets do in fact feature Gorilla Glass 2 technology on their displays. Gorilla 2 was described as being “up to 20% thinner” than the original Gorilla Glass whilst also allowing for better haptic feedback and all round responsiveness.

Corning have just recently announced Gorilla Glass 3 at CES 2013. Naturally Gorilla 3 is significantly tougher than previous designs of the product. Gorilla 3 is said to be three times more scratch resistant than Gorilla 2, will show up to 40% fewer scratches after use and maintain 50% more strength after the sheet of glass comes into heavy contact.

The guys over at engadget did manage to get their hands on some Gorilla 3 testing equipment at CES 2013, the video below shows us just how tough the new Gorilla Glass 3 actually is. Check it out for yourself!


Look for new Gorilla Glass 3 coming soon on the world’s coolest smartphones, tablets and laptops.

Samsung and Corning to Collaborate

Gorilla Glass has been a tremendous success for Corning, enjoying excellent market acceptance across mobile device industries. Handset and tablet device manufacturers are clearly driving toward higher functionality from thinner designs.

So Samsung and Corning have now announced a new joint venture, which will see Corning’s Lotus Glass technology on the face of future Galaxy smartphones. Lotus Glass promises to bring enhanced picture quality, better response times, and higher resolutions, all while also conserving power to keep your phone running longer on the modern day battery hungry smartphone.

“The intrinsic thermal consistency of Corning Lotus Glass allows it to retain its shape and quality during high-temperature processing. Decreased compaction and variation during the crystallization and activation step further reduces stress and distortions to the substrate. This enables tighter design rules in advanced backplanes for higher resolution and faster response time”.

Corning Unveils New Gorilla Glass 2 for Thinner Mobile Device Screens

Corning have announced the next generationimage of there widely accepted, damage-resistant cover glass for electronic devices, at the International Consumer Electronics Show in Las Vegas earlier this month. Gorilla Glass 1 has established itself as the best glass on market and is used on over 600 devices but the upgrades benefits are endless.

With Gorilla Glass 2 you can expect a 20 % reduction in the thickness of the glass, while maintaining the high level damage resistance, toughness, and scratch resistance showcased on Gorilla Glass 1. The thinner glass enables slimmer and sleeker devices, brighter images, and greater touch sensitivity.


Although Corning’s first generation of Gorilla Glass boasts the coverage of more than half a billion devices worldwide, they don’t have the market completely to themselves. Japan’s Asahi Glass launched a rival product called “Dragontail” last year. Speculation has surrounded the likes of Apple’s IPad 2 and Samsung’s Galaxy Nexus that in fact the “fortified glass” taht is stated on the spec is actually Asahi Glass’s quietly confident Dragontail glass shield! So you may want to keep one eye on these guys…

However, the clear benefits of Gorilla Glass 2 can provide electronics manufacturers with superior design flexibility as they address consumer demand for increasingly high-performing, touch-sensitive, and durable mobile devices.

Corning Announces Lotus Glass

Corning – The company that brought us Gorilla Glass has announced an upgrade! “Lotus Glass”, its tougher offspring.

clip_image002Corning’s recent statement read that the new material provides more “thermal and dimensional stability”, which is essential in order to endure the harsh conditions of repeated heating and cooling cycles required as part of the process of attaching high-res displays. Lotus glass is designed to be used on LCD and OLED screens and thus should give a higher resolution and faster response time.”

The thermal consistency of Corning Lotus Glass allows it to easily retain its shape and quality when experiencing high-temperature processing. Decreased compaction and variation during the crystallization and activation step further reduces stress and distortions to the substrate. This enables tighter design rules in advanced backplanes for higher resolution and faster response time.

According to Corning the end result is “a thin, portable display device that consumes less power while delivering superior picture quality”.

As screen technology continues to improve, I await anxiously for the next load of viral videos uploaded by crazy Lotus Glass device owners attempting to prove its immortality by using a variety of house hold items to batter there phone within an inch of there life!!!

The release date is not thought to be to long away and the glass is already in production. so keep your eyes peeled as LCD and OLED mobiles of the future will be kitted out with this new and improved near scratchproof glass.
