Shellac is a hard resinous secretion from the Indian lac beetle. Lac beetles emerge in swarms in parts of India at certain times of the year, and their secretions make varnish that is odorless, nontoxic, brilliantly shiny, and highly resistant to scratches and fading. It doesn’t attract dust while wet, and it dries in minutes. Even now, in an age of chemistry, shellac has scores of applications against which synthetic products cannot compete. When you go bowling, it is shellac that gives the alleys their peerless sheen, for instance.
