✦ Synopsis

India Ink, of a deep black, which gives neutral tints for halfshades, is very rare. It may be made as follows : Rub thoroughly together 8 parts lampblack, 64 parts water, and 4 parts of finely pulverized indigo. Boil until most of the water is evaporated, then add 5 parts gum arabic, 2 parts glue, and 1 part extract of chicory. Boil the mass again till it is thickened to a paste, then shape it in wooden moulds which are rubbed with olive or almond oil.--Papier-
