Who knows what they are? They have a name and they’re beautiful
Collectible antique telephone glass insulators do exist and some of them can be worth thousands of euros.
Most people have seen these objects that sit in a straight line atop telephone poles and often look like light bulbs, bowls or fancy vases. They actually have a name and are a beautiful, even lucrative (in some cases), piece of history.

While most old glass telephone insulators are worth around 20 dollars or less, some rarer pieces have been sold for thousands of euros. What’s more, few people know what these coloured pieces of glass are used for.

To understand how these old glass telephone insulators work, it may be useful to understand a little about the link between electricity, telephones and the original purpose of the story of their creation.
