Etching is the roughening of a selected area by directing a high pressure, high speed stream of sand at the surface of the glass/crystal. As the grains abrade the selected area, a "frosted" effect is produced. Color fill is then manually applied using a special paint that adheres to the etched glass. Not only will this sandblasting technique provide higher clarity of your logo or message, but adding color to your personalization will allow greater contrast and an eye-popping effect that will surely capture everyone's attention.
