Many of us see and use glass every day in many different forms and it is a very useful material. We have glass in the windows that light up our homes, in doors that can be both beautiful and strong, and in mirrors that reflect who we are. But did you know that there’s a way to make glass even tougher and safer than normal? That process, called tempering, occurs in a device called the glass tempering machine.
The glass experiences a radical transformation inside the GLASINO glass tempering furnace. The first step is to heat the glass to extremely high temperatures far hotter than we encounter in our day-to-day lives. The glass is then heat soaked before being rapidly cooled. This rapid cooling process is known as quenching. This process turns the glass into what is significantly stronger and tougher than standard glass.
The primary reason we temper glass is for safety. Tempered glass is far less dangerous than standard glass. When ordinary glass breaks, shards can fly into many sharp, jagged pieces. These pieces can be dangerous and can hurt someone. But tempered glass is special! If it does break, it breaks into small, rounded pieces that are far less likely to harm anyone. Tempered glass is also built to be more flexible, which is why this occurs. It is constructed in a manner that enables it to safely shatter instead of breaking like traditional glass.
Not only tempered glass is safer but it is also very strong. This means it can take some serious wear and tear. It is strong at high temperatures and pressure, which is a good reason for it being used in many vital applications. You will find tempered glass regularly in places such as shower doors (which have to deal with steam and water), skylights that provide sunlight, and even car windows where it needs to have strength for safety.
After heating the glass, the next step is to cool it down. This is achieved by blasting high-pressurized air on the glass. This rapid cooling process is called quenching. When this occurs, the exterior layer of the glass cools extremely fast while the interior layer remains warm for a bit longer. That difference in temperature puts stress in the glass making it many times stronger and more durable than it was previously.
This evolution is achieved through advancements in glass tempering equipment design that we have seen over many years. Convection heating is one of the most significant new concepts. Instead, this approach relies on circulating air to warm the glass rather than using infrared radiation. This type of heating is far more precise and efficient. This is critical to ensure that the glass heats uniformly, which is required to produce high-quality tempered glass.
A separate and equally critical development in glass tempering furnace design is with computer controls. These computerized systems offer extremely precise temperature control. In an alternative sequence, the glass is heated and cooled while allowing for a greater quality of tempered glass. Computer controls also assist with producing tempered glass faster and more consistently, which is great for a variety of industries and their respective needs.
