Imperial Glass Pitcher

Imperial Glass Windmill set from the 1950s.


This antique glass pitcher and six matching tumblers were given to me in the late 1950s. Each piece is marked with a G with a line through it. Although I’ve visited glass shows, I’ve never seen anything like it. What can you tell me about it?

 What’s it Worth?

A: Your antique glass water set was made by the Imperial Glass Co., which was located in “Glass City,” as Bellaire, Ohio, was known. The company was founded in 1901 by Edward Muhleman, a financier and former riverboat captain who wanted to build the world’s largest glassmaking factory. The company’s first catalog listed 15 lines of tableware! Imperial Glass continued until 1984.

Not all Imperial pieces are marked, and the company used several different markings over the years. Your seven Windmill pattern pieces have a G superimposed over a stylized I, a mark the company used from 1951-1972. In perfect condition, this antique glass water set in pumpkin-marigold is worth about $445.
