Vintage Glass Insulators T-Shirt

Glass Insulators are Unique pieces of our History. 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. Production of these little beauties ended in the 1970's. Glass insulators were the means of insulating the early communication wires starting in the later 1800s. The production of glass insulators spans a time line over 100 years with many changes effecting the design and use. There is quite a history behind these colorful chunks of glass that have been made obsolete by todays new technology. Today open wire is a site rarely seen that mostly resides along railroad tracks for communication signals but these too are quickly disappearing from our landscape. By collecting these little glass beauties you are taking part in preserving a piece of history long forgotten or even unknown from the minds of many.
