Various insulators made by the California Glass Insulator Co. 1912-1916.
I collect antique glass insulators. For roughly 100 years between 1850 and 1950 insulators for telegraph, telephone and power distribution were molded from glass. The different shades of color was usually not intentional but caused by the minerals and additives put into the mix during the glass making process. What I and most other collectors have found that these once solely utilitarian artifacts from the beginnings of the information age now offer us an almost artistic like display that is very pleasing to the eye. Collectors are also doing a service to future generations by preserving this unique part of the world's communications history.
I display my prized California collection in a west facing window where they catch the afternoon sun. My wife has even modeled the rest of the room's decor around the soft pastels of the hundred year old insulators.
