Abstract:
1. A method of creating a pigmented image on a stone substrate comprising the steps of: positioning the stone substrate relative to a laser engraving apparatus; masking the stone substrate in an image area in which the image is to be created with a first mask layer; operating the laser engraving apparatus in a pattern over the masked area at a sufficient power level to burn through the mask and vitrify the stone substrate to thereby form a first set of vitrified pits in the stone substrate; applying a first layer of pigmented paint over the image area to any remaining first mask layer in the image area and to the first set of vitrified pits; curing the first layer of pigmented paint; removing any remaining first mask layer.
