Ink

A liquid containing various pigments used for drawing or writing with a pen or brush. Early varieties of ink are Indian ink, various natural dyes made from metals, the husk or outer covering of nuts or seeds, and sea creatures like the squid. India ink is black in color and orginated in Asia. Walnut ink and [iron-gall nut ink]? were made and used by many of the early masters to obtain the golden brown ink used for drawing.
