Shellac is an ingredient used in a variety of products, such as furniture polish, varnishes, and sealants. It is made from the secretions of the female lac bug, which is native to India and Thailand. The RESIN, which is a five-letter word, is one of the main components of shellac. It is a natural polymer that is produced by the lac bug and is used to bind the other ingredients together. The RESIN is also used to give shellac its glossy finish.
