Scope note:

Vulcanite is an old trade name for a dark, brittle, moldable hard rubber that was produced by heating (‘vulcanizing’) a preparation of india rubber and sulfur. It was marketed in the U.S. as vulcanite and in England as ebonite. Vulcanite was used for small items such as buttons, brooches, and combs, finishes on camera bodies, and for insulation.
