Humans have been collecting interesting items ranging from shells to glass beads and precious metals for thousands of years. For those who collect glass, nothing is more valuable or as eye-catching as Vaseline glass or uranium glass.

“Vaseline” is a term for glass products that have been colored using the highly radioactive metal uranium. But why do people collect this potentially dangerous and unusual form of glass?

In the modern era, we associate the radioactive element uranium with atomic weapons capable of destroying entire nations.

Vaseline Glass Glows Under Black Lights

Uranium glass was coined in the early 20th century when artisans noticed that the uranium colorant used in finished products resembled petroleum jelly.

The uranium within the vaseline glows when placed under a black light, giving it the unique appearance it’s celebrated for. 

Is Uranium Glass Actually Dangerous?

The hazardous health risks associated with uranium were fully understood by the 1940s, according to The Science Times.

Since this period, many people have been hesitant to handle or even own any kind of uranium glass due to fears of radiation poisoning. Yet, it’s much safer than most imagine.

Vaseline Glass is Deemed Relatively Safe

Using a Geiger counter, a device used to measure radiation, anyone can test how much uranium is in their Vaseline glass collectible.

However, the level of radioactivity is relatively low, meaning that it doesn’t pose a health risk so long as it’s stored and handled correctly.
