India ink was first invented in China as early as 2500 BC, during Neolithic China. The term India ink however, was coined by the English due to the later trade with India.
Ink drawings have a very long artistic tradition. It lends drawings expression and durability and can also be combined with many other drawing techniques. This includes being painted over with transparent colors without smudging as India ink is waterproof when dry.
Other characteristics include high light resistance, odor-free, acid-free and pH neutral.
