What is Bakelite?
Bakelite is a castable, fire resistant plastic that was invented by Leo Baekeland in 1909. It was originally used for industrial purposes, until jewelry makers found that its light weight made Bakelite a perfect choice for designing and manufacturing inexpensive bracelets, rings, pins and other jewelry.
Bakelite jewelry became especially popular in the 1930's and 1940's, after a wider assortment of colors was introduced. The new batch of Bakelite colors captured the imagination of more and more jewelry companies. Coco Chanel was one famous designer who offered Bakelite jewelry and accessories.
