Antique EAPG Moon and Star Clear Glass Platter Serving Bowl UV Glow Manganese

Under standard ambient daylight, this elegant antique presents as perfectly transparent, clear crystal glass with zero native green or yellow tinting. However, when placed under a 365nm UV blacklight flashlight, it illuminates with an incredibly bright, uniform neon lime-green glow! This brilliant reaction is a result of natural manganese dioxide used historically as a clarifying agent to neutralize iron impurities. A spectacular crossover piece for EAPG purists and UV glass displays!
