What is the difference between Depression glass and uranium glass?
Depression glass, clear or colored-but-translucent glassware, became popular during—you guessed it—the Great Depression. ... Uranium glass, meanwhile, is glassware that was made with uranium oxide. These pieces range from yellow to green. The use of uranium in glass manufacturing dates back to the ancient Romans.
Is uranium glass safe to touch?
Uranium glass also fluoresces bright green under ultraviolet light and can register above background radiation on a sufficiently sensitive Geiger counter, although most pieces of uranium glass are considered to be harmless and only negligibly radioactive.
Why did they use uranium in glass?

Why does uranium glow under UV light?
The uranium fluoresces under UV light because the UV excites the electrons above the ground state and gives off photons as the electrons transition back to the ground state .” Sure, everybody knows that. “The fluorescence is just an inherent property of the uranyl compound in the glass.” Natch.
