Glass that glows in a blacklight was the rage in artistic borosilicate glassblowing in recent years, also. The physics behind this is pretty interesting (electrons jumping levels and releasing excess energy). We all started carrying around UV flashlights at shows. A US company called Northstar collaborated with Gaffer Glass from NZ to make a modern borosilicate uranium glass. https://northstarglass.com/product/ns-137-ill-umanati/ https://northstarglass.com/product/ns-137-ill-umanati/ Along with their competitor Glass Alchemy, they also make several other formulas that fluoresce different colors like pink and blue.
