Hello everybody,

I was hoping if anybody could tell me something about this type of glass, that I know of but am unfamiliar with.

I did not know VSL did neodymium glass, just for fun I tried under uv light to see what happens and the thing lits up but all violet. This vase dates from the period 1951-1958 and it shows blue on the image, but as I'm standing next to it, the colour is fluorescent pink. On the image in the dark, you can see some pink on the left, while actually the whole vase has this colour but for some reason does not come through on the photo. Is it normal for this type of glass to react like that under uv light?

Nice one. Neodymium glass should look different colours in fluorescent and incandescent light. I don't know what that UV effect is but lead crystal often looks bluish under UV

Thanks for that Christine, I did not know.


Next to a lamp it gets an aqua marine like colour. Again, doesn't  show well but the colour is throughout the piece.

I finally managed to get the colour that I mentioned before on an image, just with a proper camera. I haven't worked on the image or touched it up, tis is what I get with UV light. I've got a total of 8 different colours with this piece, depending on the type of light. This pink shows up with UV, and other colours vary between mauve, violet, blue, blue-grey and dark grey with daylight, ceiling light, a torch shining inside it shows bright blue, camera flash and it goes grey, sideboard lamp shows agua-marine/turquoise … and it goes on and on...very entertaining but it's wearing me out.

I had a bowl like that (in that under certain light it just views as a dull grey almost grey transparent glass if you like.) I'll see if I can find pics on the board somewhere.
It was bright green in the charity shop I bought it from. Looked fabulous (very Scandinavian looking).
Got it home, unpacked the bag in great excitement ... and what came out was a knicker-elastic pink bowl.  Hugely disappointing.
I sold it to a friend in the end,  who has displayed it under a fabulous funky neon light thing, where it views as pink in the daylight but goes green when she turns on that light in her sitting room. 

Edit - Bowl is here - there may be some info that might help you search - rare earths? dichroic?

Looks like you've enjoyed yourself too, it really is difficult trying to show what you're talking about with this type of glass.

I've taken several pictures and these are the ones that resemble most to what i'm seeing with different lightsources.

The bright pink one in the post above is taken with UV light, as I mentioned before. I've left the piece in place and switched on the main ceiling light, and it turned a darker violet if not mauve, darker than the  colour by daylight on my coffee table, at the very top of this page.
I then switched off the light, and held a small LED torch in it, and it turned bright blue. Finally, I took a picture with flash and it turned dark grey.

I then placed the vase on a sideboard … (yes, some people still have sideboards  ) … switched on another ceiling light but here it's closer to it and it turned a bit more violet (the blue is a reflection of the telly) ....switched it off, lit the lamp next to it, and it turns to this nice aqua-marine type of  colour … can't think of what else to call it.

Nice pictures and a very good visual of the colour changes under lighting.
