New Delhi. People do not have many types of information related to cars. Millions of people travel by car every day. However, people often do not know small things related to cars. Similarly, many people do not know why black dots are present on the windshield. People often see black dots on the windshield of a car. But, many people may consider it just a design. In such a situation, let us now tell you why these happen?
The black dots on the windshield and windows and the black rims around them are there for a special reason other than design. It actually refers to the process of making car windows. In fact, since the 1950s and 60s, car manufacturers began using adhesive materials to hold car windows in place instead of metal trim.
By applying this adhesive material the work got better but it did not look good enough. These black rims seen in car windows or windshield are called frits. These frits and the black dots visible on their borders are made of ceramic paint. These frits are meant to hide an unsightly, but very important adhesive material.

Also since these painted rims are actually baked into the window. These hold the glue in place, which in turn holds the windows in place. As for the dots, they create a smooth transition from thick black lines to window transparency. Also, these dots are not placed randomly. These are positioned in a particular halftone pattern. Where the black dots become smaller towards transparency. These look better on the eyes. However, despite this, these dots are not just for decoration.
Apart from visual effects, their other function is to provide temperature control. So that the glass of the window and windshield can be bent in the same way as the glass was heated. Black patent glass heats up faster than other windows. In such a situation, the dots distribute the heat a little more evenly, which prevents the windshield from warping in the heat.
