Commercial whaling in the United States dates to the 17th century in New England. The industry peaked in 1846–1852, and New Bedford, Massachusetts, sent out its last whaler, the John R. Mantra, in 1927. The Whaling industry was engaged with the production of three different raw materials: whale oil, spermaceti oil, and whalebone. Whale oil was the result of "trying-out" whale blubber by heating in water. It was a primary lubricant for machinery, whose expansion through the Industrial Revolution depended upon before the development of petroleum-based lubricants in the second half of the 19th century. Once the prized blubber and spermacetti had been extracted from the whale, the remaining majority of the carcass was discarded.
