THE EVOLUTION OF GLASS

Documenting History

Founded in July 1975, the NDGS aims to study, research, and educate the public about the history, patterns, and manufacturing techniques of Duncan Glass. We celebrate the men and women who made this artistry possible and highlight the glass industry’s significant impact on the economic development of Washington County and the surrounding region.
