Stone surfacing is the whole range of operations which, after sawing or milling, give the surface its final polish. They take place as follows: - Roughing (or dressing) which removes the flaws caused by sawing; - Smoothing, which eliminates the scratches left by the abrasive during the previous operation; - Polishing, which gives the stone sufficient finish to take the final glazing; - Glazing, the final operation using a flat plate, in which the diamond plays no part
