What is "lac lake"

Lac \Lac\, n. [Per. lak; akin to Skr. l[=a]ksh[=a]: cf. F. lague, It. & NL. lacca. Cf. Lake a color, Lacquer, Litmus.] A resinous substance produced mainly on the banyan tree, but to some extent on other trees, by the Laccifer lacca (formerly Coccus lacca), a scale-shaped insect, the female of which fixes herself on the bark, and exudes from the margin of her body this resinous substance.

Note: Stick-lac is the substance in its natural state, incrusting small twigs. When broken off, and the coloring matter partly removed, the granular residuum is called seed-lac. When melted, and reduced to a thin crust, it is called shell-lac or shellac. Lac is an important ingredient in sealing wax, dyes, varnishes, and lacquers.
