Etching refers to the technique of creating art on the surface of glass by applying acidic, caustic, or abrasive substances. Traditionally this was done after the glass was blown or cast.

 

Typically, "glass etching cream" available from art supply stores consists of fluoride compounds, such as sodium fluoride and hydrogen fluoride (very dangerous). The fluoridation of the glass (which is a network covalent solid of silicon dioxide molecules) causes the characteristic rough, translucent qualities of frosted glass.

Abrasive sandblasting is also a common technique for creating patterns in glassware, creating a "frosted" look to the glass. High pressure air mixed with an abrasive material cuts away at the glass surface to create the effect. The longer the stream of air and abrasive material are focused in one spot, the deeper the cut will be. Sandblasting is often used for removing unwanted items that have stuck to the glass or as a decorative purpose on gifted and personal items.
