What Is The Purpose Of Those Little Black Dots On The Edge Of Your Car Windscreen? Mystery Solved


Although most of us are well-versed with the purpose of objects like the ashtray, courtesy light, and back mirror, yet, there still are many features of your automobile which may seem useless to you but serve a greater purpose. One such feature is the presence of black dots which stare at you, right in the face, from your windshield.

As it turns out, these black bands, called the frit, are baked in a ceramic paint. Your car’s windshield is held in its place thanks to a urethane sealant, which also keeps out the water during rainfall. However, the sealant can deteriorate on exposure to sun’s ultraviolet rays. Therefore, the frit protects it from excessive sunlight exposure. Besides that, the frit also helps in covering up the glue on the edge of the windshield, which would otherwise ruin the aesthetics of the car.

The black dots of varying gradient that rise from the frit make your car look aesthetically appealing as they form a nice contrast with the windshield.

The purpose of the presence of these black dots is certainly not the most important piece of information which you would learn all day. But it is still better to know about it rather than staying ignorant!

    OK, I guessed wrong. My guess was they were there to provide a more gradual temperature gradient from the black edge inward to the clear glass to help keep the glass from shattering out in the hot sun. If they are there solely for cosmetic reasons, a solid line of paint would be much easier to apply than all those dots, wouldn’t it?
