This is a mechanical procedure that consists of exposing glass (or other types of materials) to a jet of sand and air capable of eroding the surface. The jet, suitably calibrated, may be used to treat the entire panel or a specific part of it.

Sand blasting proves to be particularly useful as it enables transparency to be eliminated without hindering the passage of light. This technique can also be used for marketing and promotional purposes to create writing, brands and logos on glass panels and shop windows, professional studios, offices and hotels.
