For many years, American inventor Charles Goodyear had been experimenting with vulcanization, the process of turning raw rubber into a useful, pliable, non-rotting substance, and perfected the process in 1839. Not long after, Charles' brother Nelson figured out how to turn the soft, malleable substance into a hard rubber (hard vulcanite) which he patented in 1851. This 3” long cardboard box contains a hard rubber hair pin manufactured by The India Rubber Comb Company. An interesting Civil War period ladies in good condition.
