The black dots on a car's windshield are called frits. They are made of black enamel and are baked onto the glass during the manufacturing process. The frits serve several important functions:
- They provide a rough surface for the adhesive that bonds the windshield to the car frame, ensuring a secure attachment.
- They hide the adhesive from view, providing a more polished appearance to the windshield.
- The dots are arranged in a halftone pattern to create a gradual transition from the black frit to the transparent glass, which is more aesthetically pleasing.
- They help distribute heat evenly during the bending and installation of the glass, preventing warping.
In summary, the black dots, or frits, are a crucial component of the windshield, serving both functional and aesthetic purposes
