Cadmium glass

The key chromophore responsible for the fluorescence is allegedly cadmium sulfide. Since finding this goblet, I've found a few Czech glass beads that seem to be made of the same stuff, but so far I haven't spotted any obvious pointers from my previous attempts to data-mine the Czech glassmakers' color-coding system wrt uranium glass-- and even in the strand that I found at Global Beads down in Mountain View, there are several distinctly different levels of fluorescence brightness despite all of the beads looking identical under normal viewing conditions. I suppose that's not too surprising, considering the difference just between the inside (middle image, UV light from top) and outside (rightmost image, UV light near bottom) of the goblet.
