The twigs are scraped to remove the incrustation; this crude lac material is known as stick lac. If the stick lac is crushed, the wood splinters and other foreign materials removed, and the red coloring matter produced by the insects dissolved out, the residue when dried is seed lac. Seed lac is melted, filtered, and stretched into thin sheets, which are broken into flakes when cool. Orange-colored shellac is made from these flakes by dissolving them in alcohol.
