The Other Side of Glass: The frosted look

Take a look at the picture. Do you know how this design was made? Most of the glass fabricators will know the various ways to achieve this frosted look.Let us define each different technique for us to know the advantages of one type to another. 

Glass engraving is a process of decorating a glass with the use of engraving tools to leave a translucent finish. Tools used are diamond and tungsten carbide. Engraving produces a simple monotone or in a shade of black and white, depending on air pressure, varying angle, type of engraving used.

Acid etching is done by using a strong acid to glass to create a design. Most commonly used acid for this process is hydrofluoric acid. It can be in a form of powder diluted in water or a cream. Etching produces a smooth frosted surface that can be easily cleaned.

Sandblasting is a process of applying an abrasive material at a surface using a compressed air. Some abrasive materials used for this process are sand, aluminum oxide, silicon carbide, and glass beads. The blasted portion has a rough surface that dirt and fingerprint oil tends to accumulate. But don't you worry because there is a sandblast sealer available in the market which applies to the sandblasted surface to reduce fingerprint.

Other techniques use a sticker or paint finish to create a translucent look. However, this will not last long as it can be easily peeled off on a glass surface.
