Shellac is scraped from the bark of the trees where the female lac bug, Kerria lacca, Order Hemiptera, Family Coccidae[1] secretes it to form a tunnel-like tube as it traverses the branches of tree. The insects suck the sap of the tree and excrete "stick-lac" almost constantly. The raw shellac, which contains bark shavings and lac bug parts, is placed in canvas tubes (much like long socks) and heated over a fire. This causes the shellac to liquefy, and it seeps out of the canvas leaving the bark and bug parts behind. The thick sticky shellac is then dried into a flat sheet and broken up into flakes when dried, or dried into "buttons" (pucks/cakes), and then bagged and sold. The end-user then mixes it with denatured alcohol on-site a few days prior to use in order to dissolve the flakes and make liquid shellac
