One of the niche hobbies I have is insulator collecting. Insulators are the glass/ceramic parts that keep electrical lines from shorting out:
They come in all sorts of colors and shapes, some rare, some common:
They can be the size of a fist, or long chains:
The hobby is dominated by retired lineworkers. But it deserves so much more attention! They are often referred to as "crown jewels of the wire". Anyway, this is my niche infodump. Thanks for reading!
