Sandblasting and Acid Etching

To create an etched window or door reproduction a rubbing or photograph of the original is used which is then transfered onto a mask on the glass. This can be tape, vinyl, bitumen or any substance able to protect the glass from the etching process – sandblast or acid.

After the mask is applied the panels are then sandblasted to create the frosted/ etched pattern. If permanent, most etching on glass today is done by sandblasting. Traditionally hydrofluoric acid was used. Acid is still used by some glass artists as it is still the best way to create certain effects.
