Comparing Types of “Frosted” Glass

Glass that has translucent or semi-opaque properties is often referred to as “frosted” glass. There are two primary ways to achieve this effect:

  • Acid-etching: Acid is applied to one or both sides of clear, low-iron, or colored float glass. The acid “attacks” the glass surface, breaking it down to achieve the desired translucent look and smooth, satiny feel.

  • Sandblasting: Flat glass is blasted with sand or other abrasive materials at high pressures. The particles etch the surface of the glass to obtain uniform or multi-relief motifs, depending on the desired pattern and overall design.
