Sandarach

Sandarach, the mastic-like resin which exudes from the coniferous Callitris quadrivalvis of the Atlas Mountains, from C. sinensis in China and from C. verrucosa, C. robusta, C. cupressiformis, and C. Reissii, known as "pine gum" in Australia. It is an important ingredient in spirit-varnishes. It is chiefly shipped from Mogador.
