In construction and glazing, ceramic frit refers to a specialized enamel made of glass particles that is fused onto the surface of glass at high temperatures. This coating is permanently baked into the glass during the tempering process, creating a durable and decorative finish. Ceramic frit is commonly used to add color, patterns, shading, or text to glass without compromising the material’s strength or clarity.

Ceramic frit is widely applied in both residential and commercial construction, particularly in curtain walls, spandrel glass, and decorative interior features. In residential settings, you might see fritted glass used in shower enclosures, room dividers, or entry doors to add privacy while still allowing light transmission. In commercial buildings, fritted glass is often used for energy efficiency and glare control, especially on large façades. Unlike films or paints applied post-production, frit is integral to the glass itself and will not peel or degrade over time. It’s also distinct from tinted glass in that it provides customizable patterns or designs rather than uniform color.
