Cadmium together with sulphur forms cadmium sulfide and results in deep yellow color, often used in glazes. Together with selenium and sulphur it yields shades of bright red and orange — causing it to glow yellow, orange or red under 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. The unit of measurement for light wavelengths is the nanometer (nm). Ultraviolet light is generally considered to be from 200 nm to 400 nm.
