Tempered glass is known for its strength as well as its ability to shatter into tiny and relatively harmless pieces. It can be bought from stainless steel suppliers in the Philippines. The glass is used in products that are either in constant contact with the human body or are used as a safety measure for them. It is also integrated into areas with a high risk of fractures such as buildings or automobiles.

Examples of tempered glass in items are screen protectors for cell phones, glass doors for showers, and microwaves. These can be purchased at trusted suppliers such as One Sky Philippines. Here is a timeline of the history of tempered glass.


How Is Tempered Glass Made?

Tempered glass is made with the annealing method. It creates tension in the middle of the glass and compression on its outer edges. This is the secret to the strength of tempered glass. Here are the three steps in the annealing methodology.

  1. Cutting
  2. Tempering
  3. Quenching

Cutting is the first part of the creation of tempered glass. The glass is cut into the set length and width. Then, an abrasive is applied to smoothen the sharp edges. Afterward, the glass is washed off of any excess debris. The glass must be properly examined in order to spot any imperfections that could cause it to break in the proceeding steps.

Tempering is the next step. The glass is fed into a tempering oven and heated to more than 600 degrees Celsius. Note that this extreme heat treatment process could cause breakage if the glass has an imperfection.

Quenching is the last step in the creation of tempered glass. The glass is removed from the tempering oven and immediately sprayed with high-pressure air. This extreme cooling process is called “quenching”. It cools the exterior faster than the center, causing tension and compression that strengthens the glass.


The Creation of Tempered Glass

The Creation Of Tempered Glass

The process of tempering glass was first created in the middle of the 17th century. In 1874, King Francois Barthelemy Alfred Royer de la Bastie discovered a kind of glass that breaks into tiny little pieces while maintaining its physical form. He heated a piece of glass until it was molten and immediately quenched it in a hot bath of oil.

In 1877, a German named Friedrich Siemens created a different version that is more commonly known as compressed glass. His process presses the glass into cool molds. This method created an even stronger kind of tempered glass.

Austrian Chemist Rudolph A. Seiden was the first to win a patent for the creation of tempered glass.


 Rise in Popularity of Tempered Glass

In 1876, American Geovge E. Rogens received a patent in Massachusetts to introduce tempered glass into drinking glasses and streetlamps. American Hugh O’Hill won a patent in New Jersey in the same year.

By 1936, tempered glass was being added on to vehicles in the United States as a form of protection. Studies were showing that people were most likely to pass away in the case of them being ejected from the vehicle during an accident. Tempered glass was chosen due to its ability to stay intact when damaged.


The Introduction of Tempered Glass to the Global Market

Tempered glass was first introduced to the global market by a Chinese company called Shanghai Yaohua Glass Factory in 1955. By 1965, another Chinese company was creating military grade glass.

By the 1970s, tempered glass was everywhere. The glass was widely promoted and became incredibly popular all over the world. It was most commonly used in the automobile, construction, and electronics industries.


Tempered Glass in Major Industries

Tempered Glass In Major Industries

Tempered glass became popular due to a number of industries. This kind of protective glass can greatly reduce the chances of extreme injuries. These can be purchased at trusted suppliers such as One Sky Philippines. Here is a list of industries and how they make use of tempered glass.


The windows of a vehicle are made of tempered glass. It can withstand the pressures from large potholes and even just the closing of the car door. A new kind of glass has been developed that combines the strength of laminated and tempered glass. These are quickly being integrated into new car models.


Windows and glass doors need to be made of a glass that can withstand constant use and possible banging. Tempered glass is used for this specific reason. Windows and doors can be suddenly and violently shut by strong winds. It is important that the kind of glass it has can withstand the impact.


In terms of electronics, tempered glass is used mainly for the protection of devices such as cell phones and computers. This kind of screen protector can withstand the wear and tear of the owner’s constant use as well as any damage that could happen from accidental falls. It can also be used for appliances that need to handle constant heat but also be observable on the inside such as ovens, coffee machines, and microwaves.


Key Takeaway

Tempered glass was created as an alternative to kinds of glass that could be harmful once broken. It can ensure your safety while providing a unique aesthetic appearance in a number of ways. The number of industries that utilize this kind of glass can attest to its durability and safety. In the Philippines, stainless steel suppliers sell tempered and other forms of protective glass. Do your research well to find the best kind of glass for you.

One Sky Aluminum: History of Aluminum Cans

What is the history of aluminum cans?

  1. 17th-century attempts
  2. Tin cans
  3. Aluminum overhaul for cans


Aluminum cans have gone through a rich history of evolution and it was the perfect solution to the age-old problem of food preservations. Today, dozens of metal fabrication companies can easily produce thousands of aluminum cans in a day. But back then, they didn’t have such capabilities. Let’s take a deep dive into the history of aluminum cans and see how far One Sky aluminum products are today.


17th Century Attempts

17th Century Attempts

Before we talk about the aluminum can itself, let’s go all the way back to when the development of the can began. Today, cans are used for food and beverage preservation. It’s a widely popular product in modern times, that’s why food preservation today is no problem at all. But in past ages, the mobility of preserved food and preserving food itself was a problem.

Traces of the idea of preserving food in cans can be traced back to 1795. Napoleon Bonaparte was looking for a way to preserve and transport food for the French military. The French military was in the middle of a war and they had difficulty with nourishing their soldiers on the battlefield. Many soldiers would not only lose their lives from enemy fire but from starvation and malnutrition as well.

Because of this difficulty, Napoleon offered 12,000 francs to someone who would invent an effective way to preserve food in massive amounts and make it easily accessible for transportations. 11 years later, in 1806, a French confectioner and the father of canning, Nicolas Appert discovered that cooked food inside a sealed jar will not go stale or spoil unless the seal broke.

Nicolas Appert developed a way to preserve food in jars by sealing the lid of a glass jar with a cork and sealing wax. This was the first time in history when food could be preserved without ruining its quality. Though his new innovation was perfected after the French War.


The Tin Can

Appert’s innovative breakthrough presented issues in terms of transportation. His glass jars were fragile and would break easily if the containers experienced any form of shock. A new packaging method had to be devised. British merchant, Peter Durand had an idea that was passed on to him by Frenchman Philippe de Girard. This new idea that he received from the Frenchman was to develop a tin can. Peter Durand patented the first tin can on 1810.

Tin cans were the ideal choice for food preservation at the time. They were cheaper to produce and easier to transport compared to glass. But this was considerably still expensive at the time. The process of producing a tin was labor-intensive. Every tin can have had to be handmade. During those times the maximum number of cans a workman could produce in a single day would only amount to around 60 cans.

Preserved food in tin cans was quite expensive for regular consumers to acquire. The target market for food preserved in tin cans was the upper class. Though these tin cans were a staple for the British Army and the Royal Navy. Around 1846, a man named Henry Evans invented a die device that helped speed up the process of can production. With this new invention, the rate at which cans were produced reached up to 6 to 60 cans an hour.

Around the first half of the 20th century, aluminum was incorporated into the production of cans. Though there were no aluminum cans till the 1960s, aluminum was used as the lid of tin cans. Making use of aluminum lids made the cans easier to open as an aluminum lid was more flexible compared to steel or tin.


Aluminum Overhaul for Cans

Aluminum Overhaul For Cans

At the end of the last World War, there was a sudden abundance of aluminum. Due to the large surplus of this metal, prices of raw aluminum dramatically dropped and many companies started to capitalize on this. The food and beverage packaging industry took advantage of the world’s excess of aluminum.

In 1960, beverage companies started producing aluminum cans as a method to store and preserve their drinks. Studies at the time showed that the public preferred aluminum cans over tin cans. This was because aluminum did a better job at preserving the taste of the packed drink. Aluminum cans were lighter and stronger compared to their predecessors, they also chill faster and keep cold longer than tin cans.

This age of aluminum cans would last until present times. Aluminum is easily recyclable and each molten aluminum can 100% be reused and remolded into new cans. This has helped us advance the technologies of food preservation.


Key Takeaway

Fast forward to modern times, aluminum cans are still being widely used today. This is because of the advantages that aluminum presents: protecting the taste and quality of the food or beverages stored, extending the shelf life of the food or beverage stored, portability, temperature retention, and lightweight and tough.
