Gorilla Glass is a thin and very tough glass type that protects cell phones, laptops and millions of other portable electronic devices.Gorilla Glass is a product of Corning, a company specializing in glass and ceramics
Compared with other types of glass, the Gorilla Glass is particularly:
- Resistant to scratches.
The hardness of the Gorilla Glass is comparable to that of the sapphire, which is 9 on the Mohs hardness scale, used for minerals. Regular glass is much softer, closer to a 7 on the Mohs scale. At the level of comparison, the diamond, hardest material on the face of the earth, has 10 on the hardness scale. Increasing hardness means you are less likely to scratch your phone, TV screen, tablet, computer or monitor in daily use or get in touch with other items such as keys in your pocket for smartphones.
How Gorilla Glass is Made
The glass is composed of a thin sheet of alkali-silicate aluminum. It is enhanced through an ion exchange process that forces large ions into the spaces between the molecules on the surface of the glass. Specifically, the glass is placed in a bath of potassium salt melted at 400 ° C, which forces the potassium ions to replace the sodium ions in the glass originally.
Larger potassium ions occupy more space between the other atoms in the glass. As the glass cools, bonded atoms produce a high level of compressive stress in the glass that helps to protect the surface from mechanical damage.
The invention of Gorilla Glass
Gorilla Glass is not a new invention. In fact, glass, originally called “Chemcor”, was developed by Corning in 1960. At that time, its practical application was only for use in race cars where a strong, lightweight glass was needed.
In 2006, Steve Jobs contacted Wendell Weeks, the CEO of Corning, seeking a strong, scratch-resistant glass for Apple’s iPhone. With the success of the iPhone, Corning glass has been adopted for use on a number of similar devices.
How do I know if my device has the Gorilla Glass?
There are two possible sources for this information. The first source is directly on the Corning website , where there is a complete list of products with Gorilla Glass. Another way is to go to the GSMArena site where you can search for your specific phone model and find out if your model uses the Gorilla Glass. There are some device models that have more than one version and one of them may not have the Gorilla Glass. It’s worth a look at both sites.
Each year, Corning evolves with its Gorilla Glass, managing to make it thinner and tougher. It is to be thought that in its next iterations, it will probably also have regenerative characteristics, that is, a way to “cover” the scratches. Let’s see where Corning will come with this technological marvel.
