Those black dots around your cars windshield arent decoration; the ceramic frit helps protect the adhesive from UV light and reduces heat-related distortion

The small black dots you see on windshields are known as frit, consisting of a ceramic enamel that is fused into the glass. This frit serves a dual purpose: it shields the polyurethane adhesive from harmful ultraviolet rays and facilitates heat expansion during production. Moreover, the dot matrix cleverly conceals adhesive lines, enhancing the overall aesthetic of the windshield.
