   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.
