Frosted glass is glass which has been rendered opaque through a process which roughens or obscures the clear surface of the class. There are numerous applications for frosted glass in both homes and businesses. In addition to purchasing frosted glass, intrepid crafters can also make it at home with a few basic supplies. Making frosted glass can be an excellent beginner craft project.

Commercially produced frosted glass is usually frosted with acid etching or sandblasting. Acid etching is used to make frosted glass with a pattern. Patterned glass sometimes appears in ornamental windows, as well as in glasses, mirrors, vases, and other glassware around the house. The pattern can be simple or extensive, and it may include floral or geometric elements. Sandblasting is used to frost an entire sheet of glass, for installation in places like bathrooms and other areas where people might want privacy.

A sheet of frosted glass is an excellent privacy aid because it admits light without allowing people to see through it. In medical offices and bathrooms, the use of a curtain or blinds would make a room gloomy and unpleasant to be in. Frosted glass, on the other hand, keeps a room light and friendly while still allowing people to be comfortable. People may also use frosted glass for privacy in entryways in urban areas, so that passerby cannot see into a home.

When making frosted glass at home, experienced etchers can use acid, but crafters can also use a frosted glass spray. The spray adheres to the glass, obscuring the clarity and creating the slightly pebbled, light look which people associate with frosted glass. Stencils are usually laid down with tight taping to ensure that the glass frosting does not seep. The spray is applied over the stencils and is allowed to dry before the stencils are pulled off, leaving a crisp pattern of frosted glass behind.

When crafters are learning to make frosted glass, they usually start out on practice pieces before moving to major projects. Once they have mastered the basics, they can start frosting windows, mirrors, and glassware around the house. Glass frosting can be accomplished on glass of any color, and can look quite striking and distinctive. Crafters who want to work with acid to produce frosted glass should take classes first, so that they can learn acid etching in a safe environment. Eye and face protection should also be worn when making frosted glass.
