Sandarac and SHELLAC are both resins used in making varnish. Sandarac is an 8-letter resin derived from the sap of the sandarac tree, which is native to North Africa and the Canary Islands. SHELLAC is a 7-letter resin made from the secretions of the lac insect, which is found in India and Thailand. Both resins are used as a protective coating for wood and other surfaces, and are also used in the production of varnish.
