Frostetched

Frostetched is a decorative surface finish applied primarily to glass and translucent polymers. It describes surfaces that display a frosted, diffuse appearance with etched or textured patterns resembling frost. The term encompasses both the overall matte texture and any patterns created by the etching or texturing process, and may refer to the resulting finish as well as to the technique used to achieve it.

Common methods include chemical etching, sandblasting (abrasive blasting), laser engraving, and controlled abrasion. Substrates include float glass, tempered glass, acrylic, and polycarbonate. The method chosen affects light diffusion, pattern resolution, surface roughness, and durability. In architectural contexts, frostetched glass is used to provide privacy while allowing natural light to pass.

Pattern options range from uniform matte finishes to intricate frost-like designs with geometric or organic motifs. Frostetched finishes can alter glare and color perception, so they are selected to balance visibility, ambiance, and privacy in interior and exterior installations.

Maintenance considerations include cleaning with non-abrasive, manufacturer-approved cleaners. Frostetched surfaces may show wear or scratching differently than clear glass and can be more sensitive to certain chemicals on plastics. The term frostetched is sometimes used as a product or brand descriptor by manufacturers.
