- Sandarac abstract "Sandarac (or sandarach) is a resin obtained from the small cypress-like tree Tetraclinis articulata. The tree is native to the northwest of Africa with a notable presence in the Southern Morocco part of the Atlas mountains. The resin exudes naturally on the stems of the tree. It is also obtained by making cuts on the bark. It solidifies when exposed to the air. It comes to commerce in the form of small solid chips, translucent, and having a delicate yellow tinge. Morocco has been the main place of origin of sandarac. A similar resin is obtained in southern Australia from some species of the Australian cypress-like trees Callitris, but the resin has not been systematically collected in Australia.Historically, especially in the Late Medieval and Renaissance era, sandarac was used to make varnish. When "varnish" was spoken of in Renaissance Italy (Italian vernice) it usually meant sandarac. Copal and other resins displaced it as equally good, less expensive varnishing materials. Nevertheless the sandarac varnish is still valued today for use as a protective coating on paintings and antiques. It gives a coat which is hard, lustrous and durable. The varnish is made by melting the resin and mixing it with (e.g.) linseed oil. Sandarac resin melts at about 150°C. to a colourless or slightly yellow liquid. Its specific gravity is about 1.04.Although it is not very strongly aromatic, sandarac resin was and is also used as an incense. The aroma has been compared to balsam.Historically sandarac was also used as a remedy for diarrhea[citation needed], particularly in the Middle East, but today this has no medicinal advantage over various other therapies. Furthermore, calligraphers may sprinkle powdered sandarac gum on paper or vellum to help writing thinner lines.Besides the resin and the varnish, the word sandarac may refer to the tree that produces the resin. Entirely separately from that, the ancient Greeks used the word sandarac to refer to an arsenic sulfide. In medieval Europe the term sandaraca also meant red lead, as well as red arsenic sulfide. The resin/varnish meaning comes from the medieval Arabs. To distinguish this meaning from the Greek meaning, it was occasionally called "Arabian sandarac" or "sandaracha Arabum" in New Latin writings. "This represents Arabic sandarus also sandalus, but the Arabic word cannot be native Arabic", says the OED.".
