SANDARACH, is a peculiar resinous substance, the product of the Thuya articulata, a small tree of the coniferous family, which grows in the northern parts of Africa, especially round Mount Atlas.

The resin comes to us in pale yellow, transparent, brittle, small tears, of a spherical or cylindrical shape. It has a faint aromatic smell, does not soften, but breaks between the teeth, fuses readily with heat, and has a specific gravity of from 1.05 to 1.09. It contains three different resins; one soluble in spirit of wine, somewhat resembling picric acid (see TURPENTIN;); one not soluble in that menstruum; and a third, soluble only in alcohol of 90 per cent. It is used as pounce-powder for strewing over paper erasures as incense, and in varnishes.
