How is Tempered Glass Made?

Glass is essential to modern design, but it can be dangerous when it breaks. That’s where tempered glass comes in. It’s a safe and reliable solution that offers natural light and views without compromising safety. Here, we’ll explore everything you need to know about tempered glass – from its impact resistance and types to its manufacturing process. 

An Overview of Tempered Glass 

Tempered glass is a type of safety glass that is treated with a special heating and cooling process to make it more resistant to breaking than regular glass. When it does break, it shatters into small, dull pieces rather than large, sharp shards that can easily cause injury. Building codes frequently require tempered glass to be used in locations where broken glass presents a significant hazard. The tempering makes the glass much tougher, so it is less likely to cause harm when it breaks. 

How is Tempered Glass Made? 

Here is the complete process of making tempered glass: 

I. Glass Preparation 

Normal glass sheets are first cut to the needed size, ensuring the glass is pristine before tempering to prevent breakage. 

II. Extreme Heating 

The prepared glass sheets are then heated in a special oven, where the temperatures reach over 1100°F. 

III. Rapid Cooling 

The red-hot glass then undergoes forced, intense blasts of cold air. This quenching causes the outer layer of glass to solidify much faster than the inside. 

IV. Compression and Tension 

As the inside of the tempered glass cools, it contracts and pulls on the already hardened, solid outer layer. This tugging force creates areas of compression and tension between the outside and inside of the glass pane. The balancing forces between the compressed outer surface and the stretched inner core give tempered glass its hallmark durability and strength. 

V. Safety and Protection 

The heating and rapid cooling transform delicate glass into a super protective solid material. 

Types of Tempered Glass 

There are five major variants of tempered safety glass:  

1. Clear Tempered Glass 

This glass goes through a heating and rapid cooling process to increase its strength but retains the same transparent and colourless look of normal glass. It provides safety without altering visibility. 

2. Tinted Tempered Glass 

While undergoing standard tempering for added durability, tinting elements, such as grey, bronze, or green tints, are also added to this glass to provide colouration. The tinting offers style and privacy, while the tempering maintains safety. 

3. Laminated Tempered Glass 

This glass combines a laminate between two layers of tempered glass to offer the benefits of laminated safety glass and strengthened tempered glass. The lamination holds glass fragments together in the event of breakage. 

4. Reflective Tempered Glass 

A reflective coating is applied to tempered glass panels to create a mirrored surface on one side, which provides an aesthetic effect and one-way privacy while retaining the strength of tempering. 

5. Frosted Tempered Glass 

The process used to give normal glass a frosted, obscured look is applied to tempered glass. This allows light to pass through while obscuring vision entirely for privacy and boosting safety.
