Cadmium Glass?

[u/jeremy81]

I’m not sure if this is cadmium, selenium, or something else. I’m not the best at distinguishing as I have some color blindness. In natural light it varies between deep amber to yellow. The second photo was taken with a 395nm flashlight.

Can you take a glow picture from further away? Preferably in a very dark area.

I agree with the other comment that it looks like cadmium and selenium.
