The decorative pattern of small black dots on car windows serves a purpose beyond aesthetics. In earlier times, when car windows needed to be securely held in place, substances like tar or glue were used for this purpose. However, while effective, these substances had a drawback they didn’t look visually pleasing.
To address this issue, car manufacturing companies introduced a technique known as “frits.” This involved placing small black dots around the edges of car windows. These dots were created using a type of ceramic paint. Their primary function was to conceal the adhesive material that was used to keep the windows in place.
Over time, this technique evolved, and the initial wide black bands gave way to a pattern of smaller black dots, which were found to be more visually appealing.
Interestingly, the positioning of these dots plays a significant role in the overall appearance of car windows. This arrangement is called the “half-tone pattern,” and it contributes to the windows’ attractiveness.
In addition to their visual role, these black dots also have a functional aspect. They help regulate the temperature of the car windows. By absorbing and distributing heat, they contribute to maintaining a more comfortable temperature inside the car.
This dual functionality enhancing the visual appeal and assisting with temperature control makes these black dots on car windows more than just a decorative pattern; they serve a practical purpose as well.
