Exciting scientific and technological advances punctuated the nineteenth century. Growth and development with regard to jewelry-making techniques and new and innovative jewelry materials were an important part of these creative endeavors. Combining imitation gems with various imitation jewelry materials had already been en vogue since the early Eighteenth century and viable replacements for faux non-metallic jewelry materials were chiefly derived from plastics and rubber.

Uncured rubber is somewhat brittle and does not have the stamina to hold up over the long term necessary to be viable for jewelry use. It was not until Charles Goodyear patented the vulcanization process in America in 1844 and Thomas Hancock did the same in England, that jewelry production with a rubber composition was possible. Vulcanization is a high-heat process that adds sulfur to the mix and renders the result more durable than rubber or plastic alone. Both gentlemen exhibited their achievements at the Great Exhibition, displaying molds of items intended to substitute for the very popular, but exceedingly brittle jet.

One of the main purveyors of vulcanite jewellery was the Britannia Rubber and Kamptulicon Company, set up in 1854 at Cannon Street in the City, with the works in the East End of London at Bow Common, “for the purpose of manufacturing in England articles invented by Mr. Goodyear.” From 1866, they placed advertisements in The Times for ” Indiarubber chaines Benoiton, wholesale and export only,” offering a full range of industrial, household and ornamental goods including “Imitation Jet (India Rubber): Albert chains, Victoria chains, long chains, Latin, Greek, Maltese and Dagmar crosses, broochesbraceletsearrings, waist-clasps, charms and trinkets, gauntlets and armlets, fancy black combs, and dressing combs,” assuring their customers that these items had the “the beauty of polish and deepness of colour of jet, without its dangerous quality of brittleness…You may dash a bracelet or chain of this material to the ground without injuring it.”1

It is also interesting to note that a more prolonged, higher sulfur process produced a material that they dubbed ebonite. As a substitute for wood, it can also be found in jewelry of the period. The result of this modified process was a material much blacker than vulcanite which could be polished and finished in the manner used for ivory.
