Uranium and vaseline glass, which glow bright green under UV light, are quite well known. However, other chemicals also glow under UV light, although not so vividly. This pair of candlesticks glow blue and pink due to the different chemicals in the glass. A high lead content is known to produce a blue response, whilst a pink glow may be caused by the presence of cadmium. #GlowingGlass #CadmiumGlass #LeadGlass #UVGlass
