I’m working on building some various prop artifacts from across the DC universe, and my goal is to make them as tactile and believable as possible. So, in instances of things like Kryptonite and Nth metal, I’d like to research as much I can about the characteristics of those materials. What real-world minerals are they most comparable to? What is the hardness of Nth metal? What kind of radiation does Kryptonite produce? All of these and more.
Is there a particular resource book or run or anything of the sort that delves into the finer details of DC’s fictional minerals?
