Difference Between Patterned Glass And Heat Strengthened Glass. In this article, you will come to know about what is patterned glass, what is heat strengthened glass, what is the main difference between patterned glass and heat strengthened glass, and much more.
Both the terms patterned glass and heat strengthened 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 patterned glass and heat strengthened glass, then differentiate between them in detail.
What Is The Main Difference Between Patterned Glass And Heat Strengthened Glass?
The main difference between patterned glass and heat strengthened glass is that the:
-Patterned glass is made by passing through the rollers that have patterns on them. It is directly poured into the rollers from the furnace. Then, it is shaped and annealed to desired thickness and size.
-Heat Strengthened glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi, which makes it stronger than annealed glass.
What Is Patterned Glass?
The first process of making the pattern glass is melting silica sand, soda, and lime are together in a tank. Then, it is passed through the rollers that have patterns on them. It is directly poured into the rollers from the furnace. Then, it is shaped and annealed to desired thickness and size. Pattern glass is a type of rolled glass. There are two types of rolled glass, one is patterned glass and the other is wired glass.
The other names for patterned glass are figured glass, obscure glass, and decorative glass. It is available in thickness of 1/8″ to 3/8″. This glass is passed through the pattern rollers and that pattern is etched on both sides of the glass. Patterned glass can be used for privacy or either decoration. The light can easily pass through the pattern glass.
What Is Heat Strengthened Glass?
Heat Strengthened Glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi for 6mm glass, which makes it stronger than annealed glass. It has more resistance to thermal loads and is stronger as compared to annealed glass.
This glass is also referred to as semi-tempered. That’s why it cannot be used as a safety glass. It cannot be cut, drilled, edge-ground, or sandblasted after the heat strengthening. Heat-strengthened glass is shattered like tempered glass, however, it got fractured into dangerous large shards.
Heat strengthened glass is used in laminated glass to give it extra strength, for example, overhead and sloped glazing.
What Are The Properties Of Glass?
The 6 main properties of glass are as under:
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.
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.
The workability of the glass is a superior property. Glass can be moulded into any shape when melted.
A glass should have visible transmittance property. It means that a visible fraction of light should pass through the glass.
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.
A glass can always be recycled. It has 100% recyclable property. It is used as a raw material in the construction industry.
