Plume Goblet 3 ” diameter 6 1/16” height. Non- flint Adams #3, Manufactured by Adams & Company, Pittsburgh, PA circa 1880. The United States Glass Company, Pittsburgh, PA, at Factory “A” after 1891. The glass is clear and any colors you see in the photographs are reflections from indoors where I photographed the piece.  The goblet has the mold marks and straw marks and bubbles and waviness common in this era of glassware. Very nice color and clarity and the impression from the mold is crisp. There is cloudiness from water standing in this goblet, I have not tried to remove it other than washing it.  Please email with questions or comments. Weight before packing. 11.90 oz.
