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.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31316723"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14070245"> <skos:prefLabel xml:lang="es">vulcanite (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9836752"> <skos:prefLabel xml:lang="ca">vulcanite (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:31:43</dct:created>  </skos:Concept></rdf:RDF>
