It is very difficult to recognize fake cut glass pieces. Fakes became a problem in the 1980s and another batch appeared in the early 2000s. The American Cut Glass Association has a collection of fakes and can identify them by checking some characteristics. How does the piece of glass fluoresce under black light (ultraviolet)? Are the shape, dimensions, and weight of the piece correct? Does it have the expected wear and minor damage from years of use? Are the signatures correct? Using these criteria the American Cut Glass Association was able to identify numerous fake cut pieces in their September 2017 issue of the associations publication, The Hobstar. Members of the American Cut Glass Association (www.cutglass.org) sell reprints of many catalogs and other publications that help identify real American cut glass.
