Difference Between Coated Glass And Gorilla Glass. In this article, you will come to know about what is coated glass, what is gorilla glass, what is the main difference between coated glass and gorilla glass, and much more.
Both the terms coated glass and gorilla glass are the types of glasses that are used in construction and for different purposes. Glass is a transparent substance that can be transparent, translucent, or brittle. The process that is used to manufacture the glass is known as the ‘fusion process’. In this process, the sand is fused with soda, lime, and various admixtures. Then this mixture is cooled rapidly, thus forming a glass.
The difference in the glasses lay in their making process. Here, we will first discuss the main difference between coated glass and gorilla glass, then differentiate between them in detail.
What Is The Main Difference Between Coated Glass And Gorilla Glass?
The main difference between coated glass and gorilla glass is that the:
–Coated Glass is produced by applying the coating to the finished glass through a process called sputter coating. Various metal oxides are sprayed in the form of thin coatings from 0.01 µm to 0.8 µm.
–Gorilla Glass is a type of toughened glass. It is made by the material alkali-aluminosilicate, which is formed by bonding aluminium, silicon, and oxygen together.
What Is Coated Glass?
Coated Glass is produced by applying the coating to the finished glass through a process called sputter coating. Various metal oxides are sprayed in the form of thin coatings from 0.01 µm to 0.8 µm. The coatings are applied by the controlled exposure of the glass to vapours.
Special coatings modify the appearance of the glass and enhance its characteristics. Like special reflection/transmission/absorption properties, scratch resistance, corrosion resistance, low maintenance, etc.
There are two types of coated glass, i.e. Hard-coat glass and Soft-coat glass.
-Hard coat is made by pouring a thin layer of metallic oxide onto a sheet of glass while the glass is still on the float line, just after it has been formed into a thickness ribbon. The metallic oxide layer actually becomes welded to the glass surface. This process makes it very difficult or hard to scratch or remove the coating therefore why it is referred to as a hard coat. Often this glass has a bluish tint to it. Low E and Self Cleaning coatings fall under this category.
-Soft Coat involves the application of silver, zinc or tin (or a combination of) to glass that has already been formed and taken off the float line. The coating is softer than online coated glass therefore why it is referred to as a soft coat. Furthermore, if silver is used (and it often is) the offline coating can oxidise if exposed to normal air. For this reason, offline coated glass must be used in an insulated glass unit (IGU).
What Is Gorilla Glass?
Gorilla glass is a type of toughened glass. It is made by the material alkali-aluminosilicate, which is formed by bonding aluminium, silicon, and oxygen together. The glass is placed in a molten salt bath for up to 400 degrees celsius. This high degree temperature triggers an ion exchange process. This forces the smaller sodium ion out of glass, eventually replacing them with larger potassium ions drawn in from salt. This makes the glass denser, giving it strength and flexibility.
Gorilla glass is developed by Corning Inc. It is a durable glass product that is used to protect the screens of smartphones, tablets, and other smart devices from scratches or cracks, thus increasing the durability of your smartphone screen. Gorilla glass is very lightweight, strong and compatible with touch screen technologies. It was first implemented in 2007 on the iPhone.
Gorilla glass is not really unbreakable, however, it is incredibly strong. The latest 6th generation of gorilla glass can survive 15 drops up to 1 meter high onto hard surfaces. It also has gone through rigorous testing by Corning Inc for flexibility, scratch resistance, and impact protection.
What Are The Properties Of Glass?
The 6 main properties of glass are as under:
1.Transparency:
The main property of glass is transparency. The more transparent the glass, the better the vision of that glass. Usually, the glasses are transparent from both sides, but there is some glass that is transparent from one side only. An example of such types of glasses are mirrors that have only one side transparency.
2.Strength:
The strength of glass is the second property of glass. It depends on the modulus of the ruptured value of glass. The glass is very brittle initially. We add admixtures and laminates to make it stronger.
3.Workability:
The workability of the glass is a superior property. Glass can be moulded into any shape when melted.
4.Transmittance:
A glass should have visible transmittance property. It means that a visible fraction of light should pass through the glass.
5.U-value:
The u-value of the glass is the amount of heat that can be passed through the glass. Like, if the glass is insulated the glass will have a lower u-value.
6.Recyclable:
A glass can always be recycled. It has 100% recyclable property. It is used as a raw material in the construction industry.
