Scrimshaw began in the late 18th or early 19th century as the art of carving whale bone and ivory aboard whale ships. The crew on whalers had plenty of leisure time between sighting and chasing whales, and the hard parts of whales were readily available on voyages that could last up to four years.In its simplest form, a tooth was removed from the lower jaw of a sperm whale and the surface was prepared by scraping and sanding until it was smooth.
The easiest way to begin an etching was to smooth a print over the tooth, prick the outline of the image with a needle and then “connect-the-dots” once the paper was removed. This allowed even unskilled craftsmen to create fine carvings. Some sailors were skilled enough to etch their drawings freehand. After the lines were finished, they were filled in with lamp black or sometimes colored pigments
