Hi and welcome :hi:
We have a fair few folk here intersted in Uranuim glass of all sorts - who may be able to help - but it would be much easier if we could see the piece without the dark lighting!
A profile shot, a shot of the rim and of the base, with the details being visible are what we need - but we also need to see what colour the glass is without the uv thing - uranium glass comes in many, many colours.
