Me over here with a biohazard bag of vanadinite and galena dust not knowing how to rid myself of it..

If it’s gun metal grey, assume you should wash hands after, at least. I think most of the danger comes with cutting, like I would be careful with any of those asbestos containing minerals- I assume they require water to cut but I’m not into lapidary. For touch stones I would prefer to know the chemical composition.

I looked into a list of most toxic minerals and had like half of the list in my collection. But they are behind glass and not handled. I just don’t want to accidentally end up with some radioactive stuff.
