Shellac

Shellac is a secretion of the lac insect Coccus lacca, found in the forests of Assam and Thailand. Freed from wood it is called "seed lac." It is soluble in alkaline solutions such as ammonia, sodium borate[?], sodium carbonate, and sodium hydroxide, and also in various organic solvents. When dissolved in acetone or alcohol, shellac yields a varnish of superior gloss and hardness. Orange shellac is bleached with sodium hypochlorite solution to form white shellac.
