I've just bought this 7cm. tall rose bowl which I assume is by Moser. Virtually all the gilding has worn off revealing the orange? underpainting which, as Christine says, indicates it is Bohemian. The pontil has been ground but a small circular scar has been left in the middle I presume to avoid any chance of grinding through the glass. I'd hoped it was Uranium and it does glow under UV but more like Manganese although it does give a slight indication on a Geiger counter.
