Still not something you'd probably want to be exposed to constantly though
Nuclear physics is neat. It's a shame it's so regulated...
Now that I think about it, that's probably a good thing. Still annoying though.

if it changes its colour.

I tried heating a sample a couple different ways, including with my propane torch. No change at 300C. I finally got it to change to grayish-blue color
with high heat, but after an hour it changed back to purple. I never saw a green color. If there is a green anhydrous version, I was not able to make
it.

I read it on atomistry. But obviously it isn't true.
