@explainingourpast: Uranium glass could be hiding in your house right now. 💚 Beginning in the 1800s, glassmakers deliberately added uranium to glass for color—and under a black light, some pieces fluoresce an incredible neon green. These radioactive antiques can still turn up in family cabinets, antique shops and flea markets today. Think you might have some sitting around your house? 👀 #UraniumGlass #VaselineGlass #Antiques #VintageFinds #WeirdHistory
