This tree grows to a height of about 150 feet in Brazil and the East Indies. In general it yields yellow colours with various mordants, which, being cheap and permanent, meet with considerable application. Old fustic is frequently used in conjunction with logwood to improve the hues obtained from the latter. Its principal colouring matter is known as morin.

With tin mordants a very brilliant orange colour is given. Sap Green is extracted from unripe buckthorn berries by boiling in water, straining, and adding a small quantity of alum. Sap green is a dark, yellowish green pigment, used for colouring confectionery, etc. It is also employed as...
