Here is an interesting ad out of Pottery & Glassware Reporter, March 7, 1889, page 23. The Pioneer Glass Company of Birmingham, Alabama included insulators as one of their product lines along with sodas, beer bottles, flasks and fruit jars.                                                                                                      
                                                                                             

This Brookfield Glass Company ad is from the private collection of NIA Historian, Rick Soller. The "Extra D.G.D.P." indicates the CD 164 Deep Groove Double Petticoat signal.

The Glassworker, January 19, 1924 issue, ran this classified ad by the Lynchburg Glass Corporation for "gatherers" -- whose job was to pull molten glass from the tank and place it into the moulds. Wages were just over $.60 an hour.

I'm sure all of us would like a nickel for every time someone has told us that they "used to shoot those insulators with a rifle when they were growing up." Western Union and Continental Rubber Works had a better idea in Telephone Engineer, June, 1948. (Courtesy of Jim Luster, Benton, Illinois.)
