LA'CONISM,
LAC'QUER, noun A kind of varnish. The basis of lackers is a solution of the substance called seed-lack or shell-lack, in spirit of wine or alcohol. Varnishes applied to metals improve their color and preserve them from tarnishing.
Lackers consist of different resins in a state of solution, of which the most common are mastick, sandarach, lack, benzoin, copal, amber, and asphalt. The menstrua are either expressed or essential oils, or spirit of wine.
LACK'ER, verb transitive To varnish; to smear over with lacker, for the purpose of improving color or preserving from tarnishing and decay.
