Frosted glass is a type of glass that has been chemically or mechanically treated to create a translucent or opaque appearance. It has a smooth, matte surface that scatters light, obscuring the view through the glass while still allowing some light to pass through. The frosted effect can be achieved through various methods, including acid etching, sandblasting, or applying a frosted film or spray.

The process of acid etching involves applying an acidic substance, such as hydrofluoric acid, to the surface of the glass. The acid reacts with the glass, creating a frosted appearance by etching the surface. Sandblasting, on the other hand, involves propelling fine particles or abrasive materials at high speeds onto the glass surface, which abrades the surface and creates a frosted effect.

Frosted glass is commonly used for privacy purposes, as it allows light to enter a space while obscuring the view. It is often utilized in windows, doors, shower enclosures, partitions, and various decorative applications. Frosted glass can come in different levels of opacity, ranging from lightly frosted to fully opaque, depending on the desired level of privacy and light transmission.
