Scrimshaw is scrollwork, engravings, and carvings done in bone or ivory. Typically it refers to the artwork created by whalers, engraved on the byproducts of whales, such as bones or cartilage. It is most commonly made out of the bones and teeth of sperm whales, the baleen of other whales, and the tusks of walruses. It takes the form of elaborate engravings in the form of pictures and lettering on the surface of the bone or tooth, with the engraving highlighted using a pigment, or, less often, small sculptures made from the same material. However, the latter really fall into the categories of ivory carving, for all carved teeth and tusks, or bone carving. The making of scrimshaw probably began on whaling ships in the late 18th century and survived until the ban on commercial whaling. The practice survives as a hobby and as a trade for commercial artisans. A maker of scrimshaw is known as a scrimshander. The word first appeared in the logbook of the brig By Chance in 1826, but the etymology is uncertain. History and materials Scrimshaw developed from the practice of sailors on whaling ships creating common tools, where the byproducts of whales were readily available. The term originally referred to the making of these tools, only later referring to works of art created by whalers in their spare time. Whale bone was ideally suited for the task, as it is easy to work and was plentiful. The widespread carving of scrimshaw was enabled when the 1815 publication of the journal of U.S. Navy Captain David Porter disclosed both the market and the source of the whale teeth, causing a surplus of whale teeth that greatly diminished their value and made them available as a material for ordinary seamen. Around this time is the earliest authenticated pictorial piece of sperm whale scrimshaw (1817). The tooth was inscribed: "This is the tooth of a sperm whale that was caught near the Galápagos Islands by the crew of the ship Adam [of London], and made 100 barrels of oil in the year 1817." Other sea animal ivories were used as alternatives to the rarer whale teeth. Walrus tusks, for example, may have been acquired in trade from indigenous walrus hunters. Scrimshaw was a leisure activity for creative whalers. Because the work of whaling was very dangerous at the best of times, whalers were unable to work at
