The Sandblasting technique is a surface treatment method for glass, where compressed air is used to spray abrasive particles (such as sand or grit) onto the glass surface.

This process is carried out using a sandblasting machine or sandblaster, which propels the sand particles onto the glass with high force to create an etched or patterned effect on the surface.

Sandblasting is beneficial because it allows for the creation of different effects on glass with varying degrees of transparency.

It can be used to create perforated designs, frosted effects, text, or intricate patterns on the glass.

The depth of the etching or pattern can be controlled by adjusting the air pressure and type of particles used.

Another type of sand-blasting glass:

Acid-Etching

Is a specialized glass fabrication process involving the application of hydrofluoric acid to annealed glass sheets or sections to give its surface a frosted look.
