Vulcanite

Part of speech: noun

Definitions

1. A resilient synthetic material derived from natural rubber that has undergone vulcanization, often used in manufacturing components and seals due to its durability and resistance properties
2. A tough and durable material made by chemically treating natural rubber through a heating process that enhances its strength and elasticity
3. A type of rubber that has been vulcanized to improve its resistance to wear, heat, and chemicals, used in industrial and consumer products

Etymology: Vulcanite was named for Vulcan, the Roman god of fire and metalworking, because the process that makes it depends on heat. In 1839, Charles Goodyear accidentally dropped a mixture of raw rubber and sulfur onto a hot stove and found that the heat turned the sticky material into a firm, elastic substance that did not melt or go brittle in cold weather. He patented the process in 1844, calling it vulcanization after the fire god, and the name for the hardened product followed the same logic. The material was not Goodyear's alone to name. The term "vulcanite" was later applied to the hard, black form of rubber produced by adding a much higher proportion of sulfur, which makes it rigid rather than flexible. Thomas Hancock, a British rival of Goodyear, developed a similar process around the same time, and the two men fought over priority in court. Vulcanite became a common material for items such as pipe stems, combs, and early electrical insulators, and it was prized for being easy to mold.
