What is Tempered Glass?
Tempered glass is made by controlled chemical and thermal treatments to increase its strength. The glass is first first heated and then rapidly cooled with help of blowers. One surface gets cooled much faster thus putting it in compression and the other surface in tension. This difference makes the glass 5 to 10 times more stronger than it was in the first place. All the technical jargon apart, you can buy one for all popular smartphones from all leading online stores for a nominal charge.
The biggest reason to choose tempered Glass is because it’s more durable. Most of these are 2.5D hardened and you won’t have to worry about your display meeting your keys or coins in your pocket. Tempered glass can also resist scratches from pointed sharp object and can even absorb shock when you occasionally drop your phone, thus protecting your display. With more severe falls, tempered glass will shatter in to small pieces but your display will remain intact.
The Tempered glass feels like a non-existent glass layer on top and while you touch it, it feels lot better than conventional plastic. Since its also more durable, the experience remains same in the long run. It is much easier to get rid of fingerprint grease as well. The conventional scratch guard on the other hand won’t feel like glass, but plastic.
