Visually Tell Difference Between Tempered & Regular Glass

When you have a glass tabletop, they want to know whether or not that glass is tempered glass or how they can visually tell the difference between tempered glass and regular glass.

It can be challenging to tell the difference between tempered and regular glass. Even those who work in a tempered glass factory often have difficulty telling the difference between tempered and regular glass. Regular and tempered glass will look similar, except that the tempered glass has gone under a heat process for the glass to become strengthened.

Visually Telling Difference Between Tempered Glass And Regular Glass

It is tough to tell the difference between tempered and regular glass visually; even those working in a tempered glass factory say it can be difficult.

Most people working in a tempered glass factory said they could tell the difference because they are experienced and can feel the glass. Through the feeling of the glass, they can feel the slight difference between tempered glass and regular glass.

For the average person who does not have this experience, it can be challenging to tell the difference between tempered glass and regular glass just by looking at the glass.

Ways To Know It Is Tempered Glass

It can be challenging to visually tell the difference between tempered glass and regular class. Here are some ways you can tell the difference between tempered and standard glass:

  • Logo In Tempered Glass – Most tempered glass manufacturers will put a small logo on the glass’s corner. This logo will help them to be able to recognize their glass and know that it is their tempered glass.
  • Logo Usually On Glass For Buildings – If you have tempered glass for a large building, shower, or even a stairway, there is probably a logo somewhere on that glass that will tell you the manufacturer’s name. This is so that the manufacturers can tell it is their glass in case of a complaint.
  • Crack The Glass – The sure way to know if it is tempered glass is if you cracked it. If the glass cracks and does not go into sharp shards or small pieces, it is tempered glass. Of course, the disadvantage is when you crack the glass, the glass can no longer be used.

Because it can be so hard to tell the difference between tempered glass and regular glass, that is why many tempered glass factories will not give you a guarantee on the glass if you insist on having the glass without any logo. In these cases, we have been told to come to the factory to inspect the glass, and once the glass leaves the factory, they will not be responsible as they no longer know if that is their glass.

The reason is that even the tempered glass factories need to verify that it is their glass, or they will not honor any guarantee. That is why they will put the logo onto the glass, so they will know that it is their glass, and there is no question that it could be someone else’s tempered glass.

The fact they need to do this tells you how hard it can be for the glass manufacturers to verify their glass once it leaves their facility. It is because tempered glass between the different manufacturers can all look very similar.

Basic Types Of Tempered Glass

There are three types of tempered glass. All these kinds of tempered glass have been heated to strengthen the glass.

The three basic types of tempered glass include:

Heat Strengthened Tempered Glass

Heat strengthens the tempered glass, sometimes called semi-tempered or semi-toughen glass. The heat strengthening process involves heating the glass to about 650 to 700°C and then allowing it to cool quickly. This type of glass is used quite a bit, such as glass table tops or other types of glass used in the home furnishing and home decor industry.

When this glass breaks, it will also break into fragments but will usually not fracture into thousands of tiny pieces as some tempered glass does.

Toughened Tempered Glass

Toughened tempered glass is the most common type of glass that is used for railings or similar structures. This glass is heated to about 700°C, making it a glass extremely strong and safer than regular glass. It is a very high-quality and good-tempered glass.

This tempered glass is heated at a higher temperature and is stronger than regular glass.

Laminate Tempered Glass

The laminate tempered glass is when tempered glass then has some film sheets added to the glass. The film sheets toughen up the glass. The advantage of laminate tempered glass is that it can be safer and UV resistant. The laminate tempered glass will shatter into small fragments.

Laminate tempered glass can also be used for soundproofing as the glass has some soundproofing properties. The laminate tempered glass will also have colors laminated onto the glass to make it colored laminate tempered glass.

It is easier to tell laminate tempered glass apart from regular glass. But most types of tempered glass are hard to tell apart from standard glass.

Why Does Some Tempered Glass Scratch? 

One of the main reasons why you may see some scratches on your tempered glass is usually due to a manufacturing defect. Tempered glass is a glass that is heated at extremely high temperatures to make it extremely hard. But if that glass is not properly cleaned before it goes into the furnace, debris can be logged onto the glass, and when you clean the glass, the debris may become dislodge on the glass and it causes a scratch.

How To Clean Tempered Glass And Other Tempered Glass Cleaning Facts

We recommend one of the best ways to clean tempered glasses is to use a mild soap and water solution and spray it onto the glass surface. Allow that solution to sit, and then you can wipe it off and buff the glass. Before you clean any of the glasses, we recommend you take a microfiber towel and get all the dust and debris off the glasses you can.

What Is The Formula Of Glass?

Glass is generally made by heating sand or a sand mixture up to a very high temperature, so the sand melts. Once the sand mixture is liquid, it can be poured and rolled into a flat glass, pressed into a shape, or blown into a piece of art glass. Once the glass mixture cools, the glass is formed.
