When it comes to protecting the screens of our beloved smartphones and tablets, tempered glass and Gorilla Glass are two popular options that come to mind. But what exactly are these materials, and how do they differ? In this article, I will explore the composition, strength, durability, and resistance to scratches and impacts of both tempered glass and Gorilla Glass in order to help you make an informed decision about which one is better suited for your device.

Tempered Glass

Definition and Composition

Tempered glass is a type of safety glass that has undergone a process of thermal or chemical treatment to increase its strength. It is made by heating regular glass to high temperatures and then rapidly cooling it, which results in compressive forces on the surface and tensile forces in the interior of the glass. This process gives tempered glass its characteristic strength and durability.

Strength and Durability

One of the key advantages of tempered glass is its exceptional strength. It is reported to be up to five times stronger than regular glass of the same thickness. This makes it highly resistant to breakage from impact, making it an ideal choice for protecting fragile devices.

Additionally, tempered glass exhibits superior durability compared to other glass types. It can withstand extreme temperatures, which reduces the risk of thermal stress-induced cracking. It is also less prone to scratches and damage from everyday wear and tear.

Resistance to Scratches and Impacts

Tempered glass boasts excellent resistance to scratches, making it less likely to accumulate unsightly marks over time. It also provides a solid defense against impacts and can absorb and distribute the force of an impact, preventing the screen from shattering. While it may crack under severe force, the shattered pieces tend to stay in place, minimizing the risk of injury.

Gorilla Glass

Definition and Composition

Gorilla Glass is a specialized type of alkali-aluminosilicate glass developed by Corning Inc. It is known for its exceptional strength, durability, and scratch resistance. Gorilla Glass undergoes an ion-exchange process in which the surface of the glass is chemically treated with potassium ions, creating a layer of compressive stress that enhances its strength.

Strength and Durability

Gorilla Glass is renowned for its impressive strength, surpassing that of regular glass. It is designed to withstand daily use and abuse, providing reliable protection for your device’s screen. With a high level of durability, Gorilla Glass can withstand scratches, drops, and knocks, ensuring that your screen remains intact even during accidental impacts.

Resistance to Scratches and Impacts

Gorilla Glass is engineered to be highly scratch-resistant, thanks to its unique composition and chemical strengthening process. It can resist the scratches and scuffs that typically occur with regular glass, maintaining the clarity and integrity of your device’s screen over time. Furthermore, Gorilla Glass is also highly resistant to impacts, with the ability to absorb shock and protect the underlying display in the event of a drop or impact.


Both tempered glass and Gorilla Glass offer significant advantages in terms of strength, durability, scratch resistance, and impact protection. While tempered glass excels in its ability to withstand extreme force and distribute impacts, Gorilla Glass is designed to be remarkably scratch-resistant and durable. When choosing between the two, consider the specific needs of your device and your personal preferences regarding screen protection.

Frequently Asked Questions

1. Can I use tempered glass and Gorilla Glass together for extra protection?

Yes, it is possible to combine tempered glass and Gorilla Glass for added screen protection. However, keep in mind that using both may result in reduced touch sensitivity, so it’s important to choose a tempered glass that is compatible with your device’s touchscreen technology.

2. Is Gorilla Glass more expensive than tempered glass?

In general, Gorilla Glass tends to be slightly more expensive than tempered glass due to its specialized manufacturing process and the reputation of the brand. However, the price difference may vary depending on the specific product and the manufacturer.

3. Can tempered glass or Gorilla Glass be repaired if it gets damaged?

While minor scratches and surface damage can sometimes be polished out, major cracks or breaks in tempered glass or Gorilla Glass generally require replacement. It’s best to consult a professional or contact the manufacturer for guidance on repair options.

4. Are there any downsides to using tempered glass or Gorilla Glass?

One possible downside of using tempered glass is that it might affect the clarity of the screen slightly, although advancements have been made to minimize this issue. Gorilla Glass, on the other hand, can be more prone to fingerprint smudges compared to some tempered glass options.

5. Can all devices use tempered glass or Gorilla Glass?

Both tempered glass and Gorilla Glass are widely available for various devices, including smartphones and tablets. However, it is essential to ensure compatibility by selecting a product specifically designed for your device’s make and model.
