 Tempered Glass and its Uses

Most of you must have heard of a tempered glass used to protect your mobile’s screens. But it’s time to find out what exactly makes a glass tempered? This glass is created in a unique way. First, the kind of glass is heated intensely and is then cooled down quickly. This process makes this glass super useful and gives it a unique structure.

A desired measurement is required to produce a tempered glass. Next, the glass is then interrogated for any faults. A faulty glass would lead to issues when the glass is being tempered, hence this is an important step.  Further, the glass undergoes a tempering process. This is where it travels through an oven or a heating machine for tempering. This process can be done in batches or even in one continuous motion. 

Further, the glass then goes through a process called “quenching”. This is where it is cooled down. This process lasts for barely any seconds. So, various nozzles are used to blast a high air pressure on the tempered glass.  As the middle of the glass cools down first, it contracts, whereas the outer surface compresses. This change allows the glass to become strong. This method is not only cheap, but it is super effective too.

Thus, there are multiple ways to use tempered glass. One of its most frequent use is that of using as a screen protector in various gadgets. Other than that, passenger windows in a vehicle are also made up of tempered glass. Moreover, shower doors, architectural glass doors and tables, and even in refrigerator trays are made up of this glass. 

It can be used in microwaves because of its ability to retain itself and its strength. Most microwave dishes are made of tempered glass. Similarly, basking ovens also have this type of glass very often. No one wants their microwave or oven dishes breaking every now and then, right? So, the right material to be used for such purposes. Moreover, it has a lot of commercial uses too.  Phone booths, escalators, stairways and even solar panels can be made using a glass which is tempered.  Isn’t it amazing how one basic resource can be used in multiple ways?

A plate glass is usually harder because of the intense heating and a gradual cooling process to make it sturdier. A tempered glass needs to be sandblasted into a glass. So, one good way is to look thoroughly at the edges of the glass. Tempered sheets have smooth and even edges because of the extra processing it goes through. Contrarily, the glass is not tempered incase the edges feel rough to touch. So, the best way to feel is run your fingers over the edges. Your fingers will work like magic, trust us!

  • Imperfections are quite visible on the surface of the glass

These imperfections are a result of the intense heating procedure. When glass get tempered it become mendable when it is super-hot, so when it is picked up using the tongs, the process leaves slight imperfections. Look closely and you will see by yourself.

  • Last resort – Score a Line 

In addition, you can create a line on the glass using a window cutting tool. But this should be a last resort, only if you plan on cutting the glass. If the glass turns out flaky and bumpy on cutting, trust it, it’s tempered one! Do not forget to wear protective eye covers before cutting the glass. It could be injurious!  

Surprisingly, a tempered glass and a normal glass break in an absolutely contrasting manner. When a tempered sheet breaks, the glass does not spread all over its surroundings. It breaks in a unique way, into small and relatively harmless pieces. This type of glass is frequently used in areas where human safety is a priority. A normal glass, on the other hand, is much more fragile and breaks into big uneven pieces that are extremely dangerous. Consequently, tis glass is used in multiple appliances and is often considered as a “safety glass”.

Laminated vs Tempered Glass- Which one is better

Tempered glass vs laminated glass

A laminated glass is made up of two pieces of glass layers. These tempered glass is clustered together around a cover of clear plastic film. The glass is first melted.  A process where all air particles and pockets are expelled is used to make a glass tempered.  To create the finished product, it is heated over and over again. A laminated glass is extremely strong since some layers are added to it. Add more layers to it, if you want to make it even stronger.

So, the addition of a plastic rubber gives it a flexibility and a good stretch. However, it is nothing like a rubber band. This allows the glass to prevent breaking unnecessarily. Originally, car windshields used laminated glass. And because of its properties, it prevents breaking into tiny pieces and keeps the passengers safe.  Unlike tempered type , windows of tall buildings and frameless glass railings are also made of laminated glass. 

Despite slight differences, both these glass works are in a similar fashion. Upon breakage, both these glass do not shatter crazily, but just break into a web-like shape. While sharing so many similarities the glass are difference in the usage. But only a thing, unlike laminated glass, tempered sheets cannot be repaired. So, the laminated glass is also more expensive than a tempered. As long as they are used properly and are maintained well, both types of glass is worth your investment. The best part about a laminated glass is that you can identify it by looking at its edges. It has a clear interlayer which helps you identify it.
