Colorful Radioactivity

Probably some of the most famous radioactive anything is Fiestaware, due to containing a brilliant orange dye made from UO3 uranium oxide. Yet another is "vaseline" or "depression" or "custard" glass, all died green with alkali-diuranates, such as Na2U2O7·6H2O or something similar. Oddly enough, almost any uranium oxide you throw in molten glass will turn into something similar, so you can throw dark black oxides into glass and still get green.

Although uranium glass and glazes are considered a thing of the past, there are a few manufacturers still out there, including private manufacturers, and a few companies have confirmed in emails that they are still making it.
