Why does it Glow? More than just Uranium Glass, Clear Glass Can Glow Under Blacklight Too!

Have you ever wondered why certain types of glass glow under blacklight? Let's explore the science behind this fascinating phenomenon.

What is Manganese Glass?

Manganese glass is a type of glass that contains manganese dioxide as a colorant. When exposed to ultraviolet (UV) light, such as blacklight, the manganese in the glass absorbs the UV radiation and then emits visible light, creating a glowing effect.

What is Cadmium Glass?

Cadmium glass, on the other hand, contains cadmium sulfide as a colorant. Similar to manganese glass, cadmium glass also glows under blacklight due to the presence of cadmium, which reacts to the UV light by emitting visible light.

Is Glowing Glass More Valuable?

While glowing glass may seem like a novelty, it can actually be more valuable to collectors. The unique glowing effect under blacklight adds an extra layer of intrigue and desirability to certain glass pieces, making them more sought after in the market.
