Which type of coating is derived from the lac resin?

The correct answer is shellac. Shellac is a natural resin obtained from the secretions of the female lac beetle, which is harvested from trees in certain regions, primarily in India and Thailand. This resin is processed and dissolved in alcohol to create shellac, which serves as a versatile coating used in woodworking, furniture finishing, and as a food gloss.

Shellac is valued for its quick-drying properties and its ability to provide a durable finish while enhancing the natural beauty of the wood. It can serve as a primer, sealer, and finish coat, which makes it a favored choice among woodworkers and refinishing enthusiasts. This specific derivation from the lac resin distinguishes shellac from other coatings like lacquer, varnish, and enamel, which are made from different chemical bases and may not possess the same characteristics.
