A mold I bought on ebay 10 years ago. The lay down egg shaker beside it is the end product. These were made at the Columbian Expo 1893 (Chicago World Fair) and were novelty shakers.
The milk glass shaker is old, the amberish shaker was blown a few years ago, I let someone borrow it and he had some shakers blown for the art glass shaker club convention. I believe it was blown at Penland in the mtns here in NC. I guess part of the mold is missing because it ended up having an extra on the base. The amber pill bottle is a bottle I got in a box lot a while back. The top piece was never sheared/cut off. Mold weighs around 12 lbs.
Well dang, that is one awesome piece! Thanks a bunch for taking the pictures and sharing! I own some slug plates, including a local one, but I'd imagine they are common compared to the entire 19th century molds themselves.
