aNewDomain.net — What’s up with the new antimicrobial Gorilla Glass from Corning? Here’s our senior tech analyst Alfred Poor with a closer look …
By now, you’ve probably heard about Corning’s Gorilla Glass. It is used as cover glass on smartphones and other mobile devices because it resists scratches and cracks much better than standard glass does.
Now there’s a new Gorilla in town. And this one has a license to kill. The latest Gorilla Glass actually will reduce the amount of bacteria that accumulates on the face of your phone, according to Corning execs who announced antimicrobial Gorilla Glass at CES 2014.
First, let’s review how Gorilla Glass gets its strength. Gorilla Glass contains sodium ions, and the sheets of glass are immersed in a bath of molten potassium salts.
The larger potassium ions trade places with the smaller sodium ions, mostly at the surface of the glass and in decreasing proportion as you move further from the surface. This is like starting with a box packed full of tennis balls. You then replace some of the tennis balls at the surface with larger softballs. You have to press down hard to get the larger balls to fit, which results in a pressure within the surface.
For Gorilla Glass, this means that in the unlikely event that a scratch or crack gets started, it is less likely to grow larger due to the compression forces in the top layer of the glass.
Corning has figured out a way to add silver ions to the mix. Silver has natural antimicrobial properties. Nano-silver particles are employed in products to fight bacteria on keyboards and combat foot odor. So, by adding silver ions to Gorilla Glass, the new composition can cut down on bacteria and other microbes that might congregate on the faceplate of your phone, execs said.
Corning representatives were very careful not to overstate the case. They did not, for that matter, go so far as to claim that the bacteria on your phone poses any particular health hazard.
But if you’re concerned about your exposure to unfriendly microbes, using a phone with antimicrobial Gorilla Glass can’t hurt. And consider: Some scientists now are reporting there’s a 1:6 chance that your smartphone has fecal matter on it.

We can’t vouch for these products, but again, a little knowledge won’t harm you any.
