Have you ever seen small black dots or black dots on the edges of the windshield and other glasses while traveling in the car and wondered what their purpose is?
This pattern of tiny black dots on car windows is nice to look at, but it’s not just for decoration. In fact, there is an interesting reason for their presence.
By the way, know that since the 1950s and 60s, these black dots have been present in car windows.
In those days, adhesives such as glue or glue were used to hold car windows in place. The material did its job very well, but it looked awful. This led to companies putting black rims on the edges of the glasses, called frits. These frits were made with ceramic paint to hide the lace material.
Gradually the frits were replaced by black dots which felt more elegant than a thick black stripe.
The position of these dots is also very important which is called the halftone pattern. Apart from making the eyes look beautiful, these dots also serve another important function. These black dots also serve to control the temperature of the glasses.
Car windows and windshields heat up in the sun, especially black painted glass. These black dots distribute the heat much better so that the windshield and mirrors are not damaged by overheating.
