Sand Blasting
Sandblasting involves the use of course ground sand to etch engrave an image on glass, crystal or other materials such as metal. An image is printed out onto a vellum film and covered by a transfer medium called a mask, the mask is then washed out, dried and placed onto the material intended for sandblasting. The item is completely covered with only the intended target image left exposed, placed inside the enclosed sand blaster unit and blasted at high pressure, the longer the item is blasted the deeper the engraving achieved.
