Electrical Insulators Illinois Electric Porcelain Co.

Hi, I found these insulators in a bag at a thrift being sold as candle holders. I thought the outline of the state of Illinois was interesting and a little research showed they are electrical insulators and made by the Illinois Electric Porcelain Company in Macomb Illinois. I find conflicting evidence of what era they may have been made in and what the exact type of insulators they are. Each is around 4 3/8" tall. The lingo can be confusing. I would really be grateful for any help and ideas on these.

 

those are delicious....and gently used....... nice !!!!

 

Many collectors of glass insulators
They all shun pottery

yours still look like candle holders !!! ...

 

I can see them as candleholders. Are they an appropriate size?

 

I just had the thought that maybe they were promotional candle holders, but I did find a few unbranded/unmarked insulators that were very similar. I have zilch for knowledge about these things, glass or pottery.

 

Did you find this site?

The 1921 EMF Electrical Year Book said the company manufactured porcelain cleats, knobs, insulators and other porcelain products for electrical purposes. President and general manager, C. W. Kettron; secretary, Charles Hanan; treasurer, W. C. Sutton.

 

I did find slightly similar searching "wet process" but the amount of types of insulators and similar porcelain items for all kinds of electrical uses is mind boggling. I had no idea.
