RESINS Sandarac
Sandarac resin is obtained from tears of the cypress Sandarac tree that grows in the Atlas region in Morocco. The gum leaks from the bark and branches of the tree and hardens in the air. In most cases, the pieces have a long/oval or cylindrical form up to 4 cm long. The resin is smooth, a yellowish-white in color and gives off a balsamic odor, slightly like turpentine.
Sandarac is one of the oldest known resins used in preserving fine paintings and furniture. Used in spirit varnishes, lacquer and dental products, sandarac provides a hard, white or transparent film that has excellent color retention. It is still used extensively to make a protective film over watercolors.
