" 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." [1913 Webster]
