Topic: Neodymium hand etched Courtiers glasses info please?

[chriss]

Hi Here's a pair of neodymium glasses which are hand (wheel?) etched with similar (but slightly different) courting courtiers in garden scenes, though the detail isn't fantastic, they are very nice. I think they are early Neodymium as they have the orange tinge which I think is found in earlier colour change glass, though they still colour change like modern Neodymium? There are no makers marks but I was hoping that someone may know something about them anyway please? Thanks Chris

These aren't great shots as I'm still trying to work out this camera, but it shows the colour change aspect of the glass

If your glass shows yellow under black light then you're looking at manganese - in frequent use circa 1860-1915.   Neodymium as a glass colourant is not known before 1927.
