The glasses show fluorescence under a 365 nm UV lamp in the dark, a feature frequently observed on certain antique glass compositions containing manganese, formerly used as a decolorizing agent. This element provides additional evidence of an older manufacture, dating from the late 19th century to the early 20th century.
