Very pretty telephone insulator from Belarus.
Just from the colors, it’s amazing to think these were simple utilitarian devices. The one on the left is from Poland, and the right is from Belarus.
Well I’m sure I could produce insulator porn if the need arose… ;)
Thanks for the watch! I should have new stuff up in the following weeks.
This came from the town of Texcoco, a city about 20 miles east of Mexico City. It was found at the glass factory on the floor under a pile of junk.
The Electrical Contractors and Maintenance Co (EC&M) of San Francisco provided electrical equipment in California in the 1870’s. The EC&M insulators were used on telegraph lines extensively in the west, yet remain relatively scarce. This aqua colored one is by far the most common, but they also come in other colors such as green, amber and cobalt blue! Some are so valuable that fakes have been made and sold to unsuspecting hobbyists.
Made by the Lima Insulator company, circa 1905. Note the crude glaze, and chips in the porcelain that were made at the factory, and were simply glazed over.
No glass insulators were known from Norway, but this may be the first example, and I own it! Porcelain is much more common there, and this matches the styles used, and “Teknoglass Moss” seems to be a Norwegian company.
Pretty glass from Chile. A very rare transposition in an unusual color. A transposition insulator is used to transpose, or cross two wires periodically along a phone line to prevent inductive interference from adjacent pairs of wires.
A most unusual glass insulator. Called a “Cutter” after the inventor, it was used by tying it to a tree or pole with wires through the holes, and then the main wire was laid into the slot at the top (insulator here is shown on it’s side). This is a nice green color, most were found in an aqua color.
