Sumi-e
This painting technique is also called Sumi-e. It is originated in China during the second half of the Tang dynasty (around 617 to 907). “Sumi” stands for the black ink made from soot; “e” means picture or painting. The black stick ink is rubbed with water on a slate stone to make liquid ink. Depending on how the ink is diluted, shades from deep black to light grey and transparent are possible. Unglued paper or silk serve as a base.
The varying concentration of the ink, dabbing the ink or moving the brush until the ink runs out, as well as the use of additional colours is typical of this type of painting technique. Sumi-e requires great dedication and concentration, because every brushstroke on paper or silk is irrevocable.
