The black dots on your windshield are called frits, and they serve several important purposes
:
- Distributing temperature evenly : Frits help distribute temperature evenly across the windshield, reducing optical distortion or "lensing" caused by the windshield heating up faster than the rest of the glass
- Preventing windshield from warping : Black-painted glass heats faster than the rest of the window, and the dots distribute the heat more evenly, preventing the windshield from warping in the heat
- Bonding the glass to the frame : The frits, which are black enamel bands, are baked around the edges of the windshield during the manufacturing process. They not only seal the union but also provide a polished appearance by concealing the adhesive
- Aesthetic purposes : Frits and the halftone pattern they create allow for a gradual decrease in size, making the transition between the dark band and the transparent glass more subtle and easier on the eyes
Frits are made from ceramic paint and are an essential component of modern car windshields, ensuring safety, temperature control, and a visually pleasing appearance
