Vulcanite "Vinyl" Heishi Trade Beads Disks
Folklore had it that these beads were made from old records but they are actually made from an early rubber product called Vulcanite. Vulcanite is a hard, moldable rubber that has been formed by ÒvulcanizingÓ natural rubber through a curing process that involves high heat and the addition of sulfur. The result is a hard substance sometimes called ÒeboniteÓ that was used in the Victorian period to make mourning jewelry, combs, ornaments and buttons. Queen Victoria was known to wear it in tribute to her deceased husband, Albert. Today vulcanite it popularly used in the form of ÒheishiÓ in strands of beads.
