n. bakelite, trademark used for any of a group of synthetic resins and plastics found in a variety of manufact

A synthetic patented in 1909, bakelite, also called catalin, was used in jewelry extensively during the U.S. Great Depression of the 1930's. Bakelite can be molded, lathe-carved, and one color can be inlaid into another, as in polka dots. The inlaid and carved pieces are especially popular with collectors today. Watch for both outright repros, and later plastics from the last 20-30 years that might be mistaken for bakelite by the inexperienced.
