This species is the plant from which the Korean yellow lacquer is 

 obtained. The Koreans ruthlessly slit every trunk which they find in the 

 woods to cause the lacquer to secrete. The lacquer is insoluble in water 

 and never deteriorates if kept therein. The yellow furniture seen in 

 Korean shops is lacquered with it. Gilibertia trifida, the Japanese species, 

 is similar in its appearance, but the resin found within the bark is color- 

 less. It is of smaller size than the Korean species, and its fruit is spherical.
