Does anyone have a list of the colour of lead glass from late 17C to 19C when seen under ultra violet light?
I am trying to identify a glass vase which appears to be late 17C, and if I knew the various colour tones of flint or lead glass over the two centuries under UV light, I could compare it with other glass items in my collection. The shape of the vase is not recorded anywhere, yet it has all the signs of being circa 1680. I have sent photos to museums, but even they have admitted defeat.
There is a paper which might help listed in this journal:
Glass Technology 2002, Volume 43C

It is :
