Shellac << shuh LAK >> is the liquid formed of resin flakes which have been dissolved in alcohol. It is used as a varnish. The flakes are the dried form of a sticky substance called lac resin (see Lac). When shellac is applied to a surface, the alcohol in the solution evaporates, leaving a shiny finish. Shellac resin flakes are yellow, orange, or reddish, but can be bleached white. Shellac is also used in the manufacture of candies, drug tablets, and printing inks; in insulating materials; and as a stiffener. See also Lacquer; Resin; Varnish.
