It was most used from the 1920s to the 1950s, especially during the 1920s and 1930s. The electrical industry was the first to take an interest in bakelite since it met the demand for an insulating material. Plugs, sockets, switches, insulators and accessories were often made of brown, black or simulated wood grain bakelite until other colours were introduced in the 1920s (Ref. 3).
