Arizona Historic Preservation recently put together a series of video presentations about how to identify materials you might find on or in historic sites, and among the topics discussed….glass insulators! All about the colors, markings, shapes, and what era they are from. Quite interesting. Any old heads on this board remember a meet up in Durand years ago where some dude was handing out insulators from the trunk of his car??

Check out the video here:

I remember buying one of those insulators. Those meets were a lot of fun.
