My DIY Decor is here with the good news that you can fix your cracked glass by using some simple things. All you need to do is to give early attention to the damage as the small glass damages can grow into the larger ones due to moisture, temperature fluctuations, or abusive treatment.

Causes of Glass Cracking

Causes of Glass Cracking

You need to know that glass cracks can occur without any impact or strike too. Here, we will let you know about some common causes for glass cracks.

  • Thermal stress: One of the main reasons for glass cracking is due to thermal stress. The glass expands in heat and ultimately breaks. Similarly, it shrinks in the cold season and causes a crack.
  • Impact crack: This is a common type of crack that occurs in a starburst pattern from the central point. It usually happens when a baseball, golf ball, or hockey ball hits your glass.
  • Pressure crack: The pressure crack appears in the shape of a curve of an hourglass. It commonly takes place in the insulated glass where there are two panes and the air inside them. It happens when the glass is installed at a very high or on a very low elevation level.

Note: If you witnessed any impact crack on the glass, you only clean the glass that is spread on your floor. Don’t ever try to remove the remaining glass yourself, as it can be dangerous and cause injuries.
