1867 George Duncan became a partner in Ripley and Co., a company founded
by Daniel C. Ripley. Geroge Duncan purchased the remainder of the company
in 1874. He then sold one-half interest to his son James E. and their
daughter Susan N. Heisey. They changed the name of the company to Geo.
Duncan & Sons. At the death of Geo. Duncan, James and Susan
purchased the remaining half of the company. In 1891 the company became
a part of the new United States Glass Company.
Geo. Duncan & Sons glass company produced several patterns of tableware.
The production of lamps was only a small portion of their business.
A glass pattern such as "Zippered Block" would have a lamp
to match the pattern. Besides "Zippered Block" there was:
"Barred Oval", "Ribbed Band", "Ainslie Block",
"Inside Rib", "Rayed Panel", 'Quarter Block",
"Diagonal Bar", "Sunken Window", "Threeface",
and "Rayed Panel".
have a few examples of the patterns listed on the left. (click to see
photos). However, I am always looking for more, especially stand lamps
with different heights. If you have any to sell, please contact me.
