Glass Insulators were first produced in the 1850's for use with telegraph lines. As technology developed insulators were needed for telephone lines, electric power lines, and other applications. In the mid 1960's a few people began collecting these glass and porcelain insulators. Today there are over 2000 collectors, and insulator clubs, national shows, and good reference books are available.
