Manganese is one of the oldest glass additives and was used in small quantities to de-colorize (remove the green tint from glass to make clear) and in higher contents to colorize glass. Manganese can be found in nearly all colors of glass. Manganese fluoresces green under 365nm UV light.

*PLEASE NOTE: Color of glass and glow may vary slightly from photographs due to variations in screen hues and nm of black light used to produce glow. — The type of Ultraviolet light and the color of visible light is determined by its wavelength.
