I've had this a couple years. It sits outside my Florida room and is used as a door-stop. It must weigh at least 12lbs. I placed a hand shovel on it to show how large it is, too lazy to locate the tape measure again.
I researched this for a number of hours when I first found it in a thrift store, and found a insulator collectors website. And I matched the NP mark on it to a company in Canada, but it clearly says USA right there.
So I have no clue. What I did learn about insulators is that they were first made of glass, but clay proved to be a better and safer conductor of electricity. And the courseness of the clay matters, I don remember why.
But I know someone...hint, hint, can tell me some facts about this?
Thanks for checking it out and knowledge is power....I need power about this...lol
I have no clue what category?
