The Dugan glass company was founded by Thomas Dugan, a cousin of Harry Northwood. About 1904 Dugan along with his partner W. G. Minnemayer bought the closed Northwood factory in Indiana, PA and opened it as the Dugan glass company. The company continued production after the Dugan’s left the company and was renamed the Diamond glass company in 1913. The company continued production until a fire destroyed the plant on June 27, 1931.  This Dugan bowl is in the Windflower Pattern and introduced by Dugan in 1910. The bowl has 10 flutes on the rim.  Flower sprays with tulip type flowers mirror each other in the stippled center of the pattern; they are surrounded by a lined ring. The edge is saw-toothed and all shapes are collar base. 

The bowls range in size from 7 1/2″ to 9″ and have several edge treatments, ruffled, ice cream shape, and round. The exterior is plain. The original mold drawing was found 10 years after the 1931 fire closed the plant in Indiana, PA.
