Hamano tsuba signed 味墨 Miboku depicting Shoki riding tiger came to restoration with entire surface suffering by deep scratches from a jeweller’s brush. On some places I found remnants of thick layer of urushi. I don’t know a purpose why was the tsuba lacquered but lacquer was removed mechanically by a fine steel jeweller’s brush, which caused the scratches. My goal was to remove scratches without affecting a carving and don’t leave any new, and to patinate it. For your idea what such work involves, such process consist not less than 15 separated steps from start to finish. Over ten physical treatments no one repeated.
Surface is celan withou scratches.
