Hi Anik, it doesn't glow, but it has the same neon-green colour towards the rim as my other pieces.
Not sure about what belongs to this range (I guess this style was in production for a long time), but despite of the shape it is very similar -- a blue blob in the clear base, and the exactly same shades of orange, pink and neon-green mixed in the top part. It has lots of wear so should have some age to it...
The (Czech) couple I bought it from had another ashtray from this range as well, similar to Astrid's piece - most part clear with the colours more in the inner part, and the typical blue blob in the base.
BTW, I have checked the other Borocrystal ashtray once under UV, but the green colour didn't respond, so not Uranium.
