[Incoming email and pictures from Los Angeles Historical Bottle Club president and early American glass collector Dave Maryo]
I recently purchased an early cut glass decanter and would like to share some pictures. The decanter was cut in the “Fisher Diamond” pattern and is attributed to Mt. Washington Glass Works. Another example of the decanter is on display at the Corning Museum. See link: Cut Decanter in Fisher Diamond Pattern with Stopper.
Mt Washington produced quality cut glass from the time the glass works started in 1827 up to 1894 when it became Pairpoint Manufacturing Company. Globular decanters were popular in America from around 1800 to the Civil War period. Early cut glass decanters had very simple designs that are referred to as rich cut. After the Civil war the cutting became more finely detailed and was referred to as brilliant cut.
