Bakelite was the world’s first synthetic plastic, invented in 1907 and was commonly used for everyday objects in the mid 20th century. Lionel used it for transformer cases well into the 1960s.

Today, Bakelite is a specialty material. Although it’s generally a strong material, there are other plastics that tend to be more durable in everyday use, and they are cheaper. Another problem with Bakelite is that it is difficult to repair, although it’s not impossible.
