Rheology of three natural lacquers, Korea, China and Japan has been studied for the storge(G'') and loss(G'''') Young''s modulus shear velocity of viscosity. The storage(G'') and loss(G'''') Young''s modulus of all lacquers are increased with increasing a frequency. The slope of storage(G'') and loss(G'''') Young''s modulus for the Japan were greater than the Korea and China by a factor of 3. The viscosity is non-linearly decreased with increasing the shear velocity in the range of 0.01∼30, which indicates non-Nowton fluid with the shear thinning. The behaviors of shear thinning for the Korea and the China appear clearly in comparison with the Japan. This might be intimately related to the degree of purity of the laquer. The Japan has a higher purity than the Korea and the China.
