One of these is not like the others, can you tell just by looking at them ? (Apart from colour) One is hiding a interesting and spooky part of history.
To the naked eye all three look the same but turn the lights out, shine a UV light and it will show its true colours !
This is uranium glass (often called Vaseline glass due to that vintage, translucent yellow-green hue). Popularized in the 19th century and through the Art Deco era, makers added small amounts of uranium oxide to the glass mix before it went into the kiln.
The result? It looks like a beautiful antique by day and a radioactive sci-fi artifact by night. And don't worry it’s perfectly safe to display.
