Skills of Nushi artisans

The lacquer applying includes the nakanuri process and the uwanuri process. By carrying out the nakanuri process to the surface whose base foundation is adjusted, the uwanuri process can be carried out smoothly and easily. In the uwanuri process, impurities are removed from the lacquer and high quality lacquer such as red lacquer, black lacquer, highly glazed lacquer and matte lacquer are used.
In order to further purify the high quality lacquer, the lacquer is repeatedly filtered through Japanese paper to remove dusts and impurities.
In the uwanuri process, the lacquer is carefully applied in a clean room by an artisan wearing cloth that does not produce dust.
Filtering of lacquer
The first step is to filter the lacquer through layers of Japanese paper. By repeating this filtering step, even a small piece of dust is removed to prepare the lacquer including no impurities.
Process of nakanuri
After the shitaji-shi artisan adjusted the base foundation, the nakanuri process is carried out. In the nakanuri process and in the processes hereafter, high quality refined lacquer is used. The lacquer is applied carefully and softly with a brush.
Kizu-mi
After the shitaji process, the surface is checked for scratches. If a scratch is found, it is repaired by filling the scratch with the kokuso lacquer and the sabi-urushi lacquer is applied over the kokuso lacquer.
Nakanuri
After the lacquer is applied with a brush, it is dried in a room where the temperature and humidity are set adequately.
Kizu-mi
After the nakanuri process, the surface is checked for scratches. If a scratch is found, the process similar to the first kizu-mi step is carried out again.
Nakanuri-togi
After the nakanuri process, the item is set on the rokuro wheel and is spun while being polished by a polising stone and water. Small dusts are called “fushi” and by polishing, the fushi can be removed to make the surface be even more smooth.
Konakanuri
After the polishing, the lacquer is further applied carefully so as to make the surface be even more smooth and durable.
Shiage-togi
Here, the surface is polished by a piece of charcoal. Since the charcoal is softer and the particles of charcoal are smaller comparing to a polishing stone, the surface can be smooth and soft and the uwanuri process can be carried out smoothly and easily.
Process of uwanuri
In the uwanuri process, the lacquer is applied with extreme care so that even a small piece of dust will not be mixed in. High quality lacquer which is prepared by filtering through layers of Japanese washi papers for 3 to 4 times is used. And the lacquer is applied evenly on the entire surface. After the lacquer is applied, the item is put in a dry bath which makes a rotation in a set period of time to be dried. In such way, through the processes of kiji(wood base) forming to uwanuri, a beautiful and durable lacquerware item is made.
