A viscid liquid, consisting of a solution of resinous matter in an oil or a volatile liquid, laid on work with a brush, or otherwise. When applied the varnish soon dries, either by evaporation or chemical action, and the resinous part forms thus a smooth, hard surface, with a beautiful gloss, capable of resisting, to a greater or less degree, the influences of air and moisture. Note: According to the sorts of solvents employed, the ordinary kinds of varnish are divided into three classes: spirit, turpentine, and oil varnishes.
