The collections consist of articles of glassware made by American manufacturers from the nineteenth century to the present day. All major manufacturers are represented, as well as many little known companies. The collection ranges from rich cut glass and high-end art glass to Depression era machine glassware and glass toilet floats, with everything else in between. The National Marble Museum is also a part of our collections. Other items connected with the glass industry include union badges and other memorabilia, tools for the manufacture of glass, and much more.
