Difference Between Annealed Glass And Tempered Glass. In this article, you will come to know about what is annealed glass, what is tempered glass, what is the main difference between annealed glass and tempered glass, and much more.
Both the terms annealed glass and tempered 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 lied in their making process. Here, we will first discuss the main difference between annealed glass and tempered glass, then differentiate between them in detail.
What Is The Main Difference Between Annealed Glass And Tempered Glass
The main difference between annealed glass and tempered glass is that the
-Annealed glass is known as standard glass. It is thermally treated. This glass is then slowly cooled down to relieve the internal stresses.
-Tempered glass is made anneal process and is cooled down rapidly, which ultimately makes the glass stronger.
What Is Annealed Glass?
Annealed glass is known as standard glass. It is thermally treated. This glass is then slowly cooled down to relieve the internal stresses. It breaks into highly harmful large and longer shards that often cause injuries.
Annealed glass is usually used as a base glass to form other types of glasses. It is the minimum standard of glass. Annealed glass is clear glass that is used in windows doors. You can use it, if safety is not the concern but the cost is.
What Is Tempered Glass?
Tempered glass used annealed process for the manufacturation, but is cooled down rapidly, which ultimately makes the glass stronger. This glass is also known as ‘Toughened Glass’. It is five times stronger than a simple glass. It has the ability to stand up to moderate heat (470°F).
Tempered Glass is also good for safety uses. This is because of the slow healing after the annealing process. When the tempered glass is broken, it is fractured into harmless small pieces. It is mainly used for safety. It has low visibility and a translucent milky-white appearance due to the blasting of the surface of the glass with sand. The tempered glass is used in shower doors, glass furniture, shelves, fire-resistant doors, mobile screen protectors, etc.
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 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 more 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.
