Urushi final polishing process. After the final lacquer layer (uwanuri) is ground flat and “dôzuri” pre-polished with fine clay tonoko and rapeseed oil, transparent urushi lacquer (kijomi, isehaya) is rubbed into the surface and wiped of completely with paper and cured in the urushi-furo. This process is repeated several times. Then the surface is polished with polishing powder migako (roiro-migaki), rapeseed oil and the fingertips. The final polishing is a dry polish done with migako and fingers only. Uwazuri can be repeated as many times necessary. For fountain pen usually between 4 and 8 layers are used.
