Magic frites: why microscopic dark patterns are applied to a car windshield
The ornament applied along the edges of the windshield is not actually a decoration at all. It has the most, which is neither, practical benefit. Why does the “visor” have black patterns, says the AvtoVzglyad portal.

If you pay attention to the windshield of a car, you will see circles of different diameters on the edges, or a strip of up to three centimeters wide. For those who did not know, and even forgot, we tell what it is.

Dark dots are the so-called frits, which appear on the glass by applying ceramic paint with a special stencil. Then the cartridges are subjected to a complex heat treatment. They do not wash off, do not tear and do not break. In addition, when touched, they represent a kind of rough surface. What is this uncomplicated ornament for?

Frits are designed to fulfill several important functions in the car. And the most important of them is protection from exposure to direct sunlight, somehow leveling the effect of reflection caused by the play of light on the joints of the body with the windshield. Simply put, frits minimize the risk of dazzling the driver while driving.

Therefore, the markings are concentrated in the middle and upper parts of the windshield (usually behind the rear-view mirror). They block ultraviolet and dim the rays entering the cabin.

In addition, the frits serve as protection against moisture penetration, because the adhesive that is applied during the assembly of the windscreen is often unevenly distributed over the surface. And the ceramic layer is an additional “tool” for sealing. By the way, for the same reason, black patterns can be partially called a decorative element that hides the flaws in the use of engineering sealant when gluing the “visor”.
