The relatively hard product of vulcanizing natural rubber with sulfur; vulcanite
a hard, black variety of vulcanite. It may be cut and polished, and is used for many small articles, as combs and buttons, and for insulating material in electric apparatus
Ebonite was a brand name for very hard rubber first obtained by Charles Goodyear by vulcanizing rubber for prolonged periods. It is about 30% to 40% sulfur. Its name comes from its intended use as an artificial substitute for ebony wood. The material is known generically as hard rubber and has formerly been called "vulcanite", although that name now refers to the mineral vulcanite.
