Aka urushi  also called Shu urushi (red lacquer) is used in the Japanese lacquer technique for surface coating and as a basis for scattering of gold powder.

1. The liquid Japanese lacquer can cause skin allergic reactions, so avoid skin contact with Urushi.

2. When handling the Urushi latex or nitrile gloves should necessarily be worn!

3. The work surface and possibly in contact with Urushi Advised skin should be cleaned immediately with Wundbenzien or organic solvents such as alcohol or acetone. Then cleaning is strongly discouraged with rapseed oil before it is washed with water and plenty of soap.

4. The work area should be well ventilated.

5. Tools such as spatulas after work should be given in a Humidity cabinet because Urushi cures in a humid environment. Brushes can be cleaned with rapseed oil or acetone. Of course with oil purified tools must not be given in the Humidity cabinet.
