Have you ever thought to yourself on how is Gorilla Glass made? Is it like how standard soda-lime glass is manufactured? There are a lot of hearsay and rumors about the manufacturing process of Gorilla Glass, and we’ll put an end to that, today!

In this article, we’ll give you a complete rundown on how Gorilla Glass is manufactured. But in order for you to understand Gorilla Glass more and better, let’s do a rundown of the most frequently asked questions revolving around the question how Gorilla Glass is made.

What is Gorilla Glass?

Gorilla Glass is a specialized type of chemically-strengthened glass that became popular in the recent decade because of its impact and influence in the smartphone and gadgets industry. The term “Gorilla Glass” was coined by the brand Corning, and its inspiration for the title was from the strength, toughness, and long-lastingness of a Gorilla.

What is the Raw Material For Gorilla Glass?

The original Gorilla Glass manufacture is a type of aluminosilicate glass that has been strengthened using the ion-exchange method, where the bigger potassium ions replace the smaller sodium ions in the glass.

There have been zero-to-minimal reports on the original composition of Gorilla Glass to be something along the lines of soda-lime glass. What’s publicly known is that it’s made from aluminosilicate glass because of its rigidity and durability.

How Come Gorilla Glass is So Strong?

Contrary to popular belief, Gorilla Glass’s strength doesn’t necessarily come from the type of material it is, alone. In fact, that’s just a piece of the puzzle. The main factor on the strength of Gorilla Glass lies on the ions it has – let us explain how and why.

The manufacturing process of Gorilla Glass involves the ion-exchange process. This is where small-sized sodium ions leave the glass’s composition and are replaced by larger and bigger potassium ions. Since these bigger potassium ions take up more space, they form a more compressive layer on the glass’s surface.

What this does in the glass is enable the potassium ions to look for more areas to fill, creating the compressive layer, making it more resistant to damage.

Is Gorilla Glass Unbreakable?

The trait of being unbreakable has been and still is one of the most common misconceptions about it. Gorilla Glass is strong, rigid, and extremely durable, but it’s not indestructible. It’s only able to resist shock, force, and temperature better than standard or traditional glass products.

So, to answer the question Gorilla Glass is not unbreakable, but it is strong, durable, and more resistant compared to other glass types.

Because of that information, let’s now discuss how durable this thing is.

How Durable is Gorilla Glass?

Determining the durability and strength of Gorilla Glass is subjective and relative to a few factors. Among these factors would include Gorilla Glass’s resistance to chemicals, heat/temperature, force and stress, and pressure.

In terms of force and impact-resistance, Gorilla Glass is known to be drop-resistant, meaning, dropping them on a rough surface would usually make them survive the fall. Gorilla Glass is known to be extremely drop resistant of up to 1.6 meters, and has been notable on a few number of devices and smartphones.

Can You Crack Gorilla Glass?

Yes, you can still crack and damage Gorilla Glass. The only thing up for discussion here is the amount of stress, force, and impact you need to do in order to do so. Let’s approach it with real-life scenarios and events.

Say you’re walking and holding your phone and you accidentally drop it. Theoretically, you wouldn’t be holding your phone one meter above the ground, so, when it drops, the glass remains unscathed. That’s where the 1.6-meter drop test comes into play, and it can survive the fall 80% of the time.

But, if we were to test it and if we were to subject it to extreme force, like maybe hammering it down, it will break and crack.

The thing about Gorilla Glass is its connection to real-world events and situations.

Gorilla Glass vs. Tempered Glass: Which One is Better?

Did you know that a lot of people still confuse tempered glass and Gorilla Glass altogether? Some think that Gorilla Glass is the same as tempered glass. Others, on the flip side, think that tempered glass is better.

Here’s a comparison of Gorilla Glass and regular glass, as told by TheSilvJEFF.

While they are two totally different and separate materials and glass products, they have points of similarities and differences. Let’s take a look at this table and discuss both of them individually and as a whole!

Characteristic or Feature

Gorilla Glass

Tempered Glass

Chemical Composition

Made from aluminosilicate glass and is chemically-strengthened via the ion-exchange method.

Regular glass and is heat-treated and annealed, achieving the strength and rigidity.


It is strong and robust, but is also flexible enough.

It is strong, but less flexible than Gorilla Glass.

Strength and Durability

The durability and strength are of a high-quality. They can even withstand premature damage.

Excellent strength and is known to be non-shattering when broken.

Impact Resistance

Engineered to be impact resistant. Less breakage from accidental drops.

Great impact resistance, too as they don’t shatter. Just a little less resistant than Gorilla Glass.

Scratch Resistance

Highly resistant to scratches, ensuring durability and a long-lasting appearance.

Resistant to scratches, but may not be as scratch-proof as Gorilla Glass.


Costlier and more expensive because of the long and complex manufacturing process.

Cheaper and more affordable than Gorilla Glass.


Smartphones, tablets, wearables, and other gadgets.

Glass doors, gadget supplementary items, household items.

Tempered glass and Gorilla Glass share the same sentiment and goal – to protect whatever it is attached to. However, Gorilla Glass is more specialized because it is a lot thinner than tempered glass. This is where the magic of Gorilla Glass comes into play, it’s durable and robust even by just having a thin surface area.

How is Gorilla Glass Made?

Figure 5: An image of how the fusion draw process is done

The manufacturing process of Gorilla Glass doesn’t fall far from its original tree – regular glass. The only difference lies with the strengthening. Here’s the process of how Gorilla Glass is made and manufactured!

Step #1: Blending and Melting

The very first step would be to get the needed raw materials, of course. Once done, they’re blended and joined together to create an accurate and precise glass composition, which undergoes melting and conditioning.

After that, the newly-molten glass will then be fed into an “isopipe.” It will overflow until it is even on both sides.

NOTE: Gorilla Glass is made from aluminosilicate glass, so the raw materials would revolve around that.

Step #2: Isopipe Fusion

The molten glass will then rejoin or fuse at the bottom of the isopipe. Following this fusion, a thin sheet of glass, measured in microns, is drawn at a downward motion. What this process ensures is a flawless surface that’s automated, never touched by human hands, which can be potential contaminants.

Step #3: Cutting and Ion Exchange

After that, the formed glass sheet or also referred to as the “mother sheet,” undergoes cutting. This will create individual glass parts that enter the ever-famous ion-exchange process.

NOTE: The ion-exchange process is among the most important and most crucial steps in the manufacturing of Gorilla Glass, as well as its strengthening.

Step #4: Ion Exchange Process

This process involves the movement of large ions into the glass surface, replacing smaller ions. Inducing a state of compression, it works to strengthen and toughen the glass product more than its original state.

Gorilla Glass is carefully and meticulously made from optimal ion exchange behavior done in a molten salt bath at approximately 400 degrees Celsius. In this process, the smaller sodium ions exit and leave the glass. They’re then replaced by larger potassium ions from the bath.

As the glass cools down, the larger ions compress and stick with each other, generating a layer of compressive stress on the surface.

Step #5: Compressive Stress Deepening

Gorilla Glass’ unique composition allows potassium ions to deeply diffuse and populate the glass surface during the ion exchange process.

What this diffusion does is create high compressive stress points that are deep within the glass, ultimately forming a durable, robust, and strong layer of compression enhancing the resistance to damage.

That’s the general process of how Gorilla Glass is made and manufactured!

Pros of Gorilla Glass

By now, you should have an idea on what the pros and advantages of Gorilla Glass are. But for the benefit of everyone and in case you’re curious about what else it can bring to the table.

Strong, Durable, and Rigid

One of the key features of Gorilla Glass is its strength, durability, and overall rigidity. It is stronger and longer-lasting than your traditional float and soda-lime glass! It can withstand regular wear and tear, as well as impact and stress!


Gorilla Glass is also known for its scratch-resistance feature, whereas only a few materials can scratch and damage it.


When dropped at a height of 1 meter or less, Gorilla Glass is guaranteed not to break and crack. It can withstand that type of force, reducing risks of breakage for daily usage.


The overall engineering of Gorilla Glass is stupendous. It is strong, robust, and highly-resistant, but it is thin and light.


Gorilla Glass is lightweight, meaning, it can be used in a wide array of uses and applications.

Versatile and Flexible

Lastly, combining all other benefits and pros above, Gorilla Glass is flexible and versatile. Many businesses and organizations use it for varying purposes.

Cons of Gorilla Glass

Some of you might have been awe-inspired by Gorilla Glass. However, let’s not forget that just like others, there are cons and drawbacks to it, too.


Gorilla Glass is pricier and more expensive than the traditional soda-lime glass we all know. It’s an extensively and comprehensively high-quality material, painting the picture why they’re costlier and more valuable.

Little-to-No Repair Options

Repairing Gorilla Glass is challenging and may require expert and professional assistance. Other materials won’t have any dent when it comes to repairing because of their structure, but Gorilla Glass is a totally different thing; it may not be as easily repaired or replaced by the end-user.

Environmental Impact

The energy it takes to create and manufacture Gorilla Glass is about one-hundredth as much energy to form sapphire. This value can be environmentally-impacting, not in a positive way.

Not 100% Shatterproof

This is the part where tempered glass is better and more useful than Gorilla Glass. Because Gorilla Glass is not subjected to highly-fluctuating temperatures and annealing, they’re not as virtually shatterproof as tempered glass.

Although they boast of high levels of resistance, they’re not indestructible.
