Good Morning/Afternoon/Evening(depending on a reader's GMT zone)
Once Miss Blue is returned here, I'll start her own thread.
Note: those glorious darker veins to the glass, in my vase's case(PI), are actually CLEAR.
The darker blue crackling is an optical collusion: whether the viewer is close or removed from the vase (save, with your nose pressed to the glass) the eye, actually, is looking through the clear glass veins to the blue of the interior of the vase. The eye and brain decide that there is a darker blue present.
The darker blue colouration appears, literally, to be present--- but it's magic.
It is, truly, not present.
Found a white rabbit instead.
