Does Tempered Glass Scratch Easily

Tempered glass doesn't scratch easily. However, that doesn't mean it won't scratch or break. You need to handle it carefully so that the panes can maintain their luster and gloss for years. Read on to learn what tempered glass is, how to keep it functional, and conditions that can cause it to break.

What is tempered glass?

Tempered glass is a type of safety glass used in applications the standard glass could pose a potential danger. It is created through extreme heating and rapid cooling↗, making it harder than normal glass. Tempered glass is stronger than “standard” or annealed glass. And unlike annealed glass, which can shatter into jagged shards when broken, tempered glass fractures into small, relatively harmless pieces.

Does tempered glass scratch easily?

Tempered glass resists scratches from sharp objects. Although the perfectly tempered glass is more resistant to scratches it should be treated with care. Use placemats and coasters to help reduce scratches.

How to care for tempered glass

There are a couple of ways to care for your tempered glass after installation.

Maintain a regular cleaning routine to keep the tempered glass free from stains. Use a damp cloth with mild soap and water to wipe away dirt and debris.
Use a soft microfiber cloth or sponge to prevent scratching the surface of the tempered glass when cleaning it. This will keep the surface smooth and shiny for a long period.
Avoid using abrasive cleaners or products on your tempered glass. These products can scratch the surface and create permanent damage that cannot be reversed or repaired.
Do not use harsh chemicals like ammonia-based cleaners on your tempered glass. These chemicals can leave streaks, dull the surface and weaken the structural integrity of glass over time.
Polish your tempered glass after cleaning it to give it extra shine. Also, remove any streaks left from cleaning solutions used for the cleaning process.

Where is tempered glass used?

As a result of its strength and breakage pattern, tempered glass is used in various demanding applications. You can find tempered glass in:

Automotive windows

The windshields on most cars are made from laminated glass (a thin layer of plastic sandwiched between two sheets of glass). However, the side and rear windows are comprised of tempered glass. Tempered glass can withstand the stress created when a car door closes, making them a staple choice for the rear windows.

Building windows

Tempered glass is common among buildings located in areas with high winds and storms. These glasses can withstand large amounts of pressure and guarantee safety. They are also common in high-rise buildings and skyscrapers because if the window were to break, the pieces would be less likely to cause injuries.

Cookware

Tempered glass cookware has several advantages over metal pots and pans. They can go directly from the stovetop to the refrigerator or freezer without breaking or shattering. Tempered glass cookware can also withstand sudden temperature changes. This means you can preheat your pan before putting food into it, which usually isn't recommended with metal pans as this can damage the pans.

Other applications

Some other applications for tempered glasses include:

Tabletop glass
Shelves and balustrades
Screen protectors (for portable devices)
The outer layer of glass in dual glazed units
Solar panels

What can cause tempered glass to break?

While tempered glass is not easy to break, it can shatter into pieces under the following conditions:

High-temperature change above 316 degrees.
Strong impact with a hard object or if hit by something extremely heavy.
Extreme pressure differences
Improper installation of tempered glass
If there is a small defect during the production phase

It is not easy for tempered glass to break. It may develop tiny cracks and chips over time, but these will not cause it to shatter suddenly or completely if not impacted by a heavy object. Learn more about tempered glass in windows and doors by reviewing the recommended blog posts below.
