Poor thing needs tlc with a soft toothbrush and lots of washing up liquid. Bright yellow  I'll go and point my UV light at some blue stuff

Unbelievably bright yellow - in a dark room it looks like a yellow and clear vase.  All the trails glow bright yellow as well 
The photographs make it look worse than it really is in terms of needing a clean - in reality it looks fine but  I shall try it with bicarbonate of soda I think. 
It's so beautiful, I'm thrilled with it.

pic of yellow glow - my camera hasn't picked it up very well but it really is amazing in a completely dark room, it turns into a bright yellow and clear vase.  The bluey colour in the pic is the purple tube reflecting off the clear crackle glass bits.

Looks like manganese to me.

I've been looking it up to try and work out what it is.    I can't see anywhere that manganese produces blue though.  It says here (see link) that copper oxide produces turquoise.  Would that glow yellow under UV light?

I had hoped it might help date it to 'before....'

Manganese doesn't produce blue but it was often routinely used in coloured glass whether it was needed or not.

Ok, thank you 
I've found this one (see link)- admittedly only vague similarities, but is this really Auguste Jean?  I know it was a Christie's auction  but I'm just wondering?

this is another one with this applied rim in the same way.  I need to find this kind of rim on a Bohemian vase  as opposed to a trailed applied zigzag.

There are a number of vases with drip rims and similarly applied feet in Truitt's Bohemian Glass 1880-1940 under Harrach. But none with the same sticky up applied serrated edge rim.  However, one in particular is a similar shape to mine though - no feet applied but has a serrated sticking up rim in the same glass as the body of the vase (i.e no drip applied rim) The whole body of the vase is the same shape as mine but larger and not crackle (page 64 no 5)

Is there any reason why my vase might not be Italian?

What prompts my query is that I've just been looking at some Empoli glass and there is one vase in Verde which has applied trails and also a 'crown' in a similar vein to my vase.  The crown is not applied, it's all part of the green body of the vase and it's tooled so not made in the same way, but the effect is the same.... it's kind of like an 'homage' to an older piece.
So I was just wondering whether mine might be Venetian and if there was anything about it that would preclude it being so?
