Abstract
This apparatus for etching designs in a substrate, such as a glass door or window, has a transparent casing having an opening to be positioned against the substrate. A manually directable sandblasting nozzle is positioned inside the casing. A device is also provided for delivering a stream of compressed air containing sandblasting grit particles to the nozzle. The transparent casing is designed to be hand-held. In use, the substrate is masked except where the pattern is to be etched, and the transparent casing is positioned against the substrate. Sandblasting in the area of the substrate covered by the casing is carried out, and the casing moved to remaining areas of the substrate for further sandblasting until the complete design is formed in the substrate. This apparatus allows attractive designs to be formed in glass doors and windows without removing the glass from its installation.
