This is a space for collectors to answer any questions about uranium glass that people may have.

I'd like to start with some questions I get pretty often (and that were recently asked by the admin of the instance, Wintermute):

How much Uranium is in the glass anyway? Should you even be holding that?

The actual uranium content in uranium glass is usually between trace amounts and 2% by weight, but you can find pieces that are up to 25% uranium by weight. (Source: ORAU Museum of Radiation and Radioactivity) Many of my pieces, when measured with a Geiger counter, are within what's considered a low-risk range of radioactivity. Some people use their uranium glass, but I prefer to keep my handling of it to a minimum.

I think it only fluoresces like this under black light, right? Does it just look like normal glass in natural light?

UV light in general causes the glass to fluoresce. Bl
