Anotations

Scope note:

A red or yellow resin obtained from the base of Tasmanian and Australian grass trees of the Xanthorrhoea family; different species produce different colors of resin. The resins are chemically similar to balsams and contain some cinnamic acid; they produce hard, insoluble films. They are used for varnishes, metal lacquers, surface finishes for leather and paper, substitutes for rosin, sealing waxes, and inks. Treatment with sulfuric acid produces a lightfast brown-black dye.
