Abstract: The present invention is directed to a new and improved method for engraving abradable surfaces such as marble, granite, slate, glass or wood and to the mask used for the engraving. The mask is formed from a porous material such as a cloth, which is covered with a photoresist emulsion. The mask is formed by selectively exposing the photoresist. To engrave a surface the mask is first positioned on the surface to be engraved and the mask is next impacted by an abrading substance. The surface not protected by the mask is abraded and a pattern is engraved into the surface. Using the present invention no chemical interaction need occur between the mask and the surface to be engraved, and only sandblasting equipment is required. The mask can be produced remote from the engraving site and stored. Two or more masks can be overlaid to engrave intricate designs.
