Pulegoso Neodymium Glass Vase

I picked this up at a thrift a few weeks ago and left it in the garage. I didnt really pay any attention to it as I figured it was a Chinese Murano knock off. I was looking at it and did a search on "vase with thousands if bubbles" just, well, because. Anyway something came up about using phosphorus to get the bubbles so I went to see if it reacted under a black light. Most of the lights in the house have been changed over to enrgy savers and just a couple are the old fashion bulbs.
Going from my closet, which is incandescent I saw it was changing from purple to blue. I had to look at it a few times for the color change to register in my head
Questions for the forum:
Are pieces like this still being made? If so, do you know what country produces it?
I was wondering, who might have made it and when.  It's seems fairly modern to me, the wavy glass and the three pinches around the body . It also has the applied glass around the top and the bottom is polished but concave.
it is 6" high and 1lb 8 oz
Judging with what little I know, I don't think it's Murano do to the bottom finish
Thank you and enjoy the pictures! ( I love this vase!)

Neodymium glass has been used recently by several glassmakers, Caithness used it a lot, likewise various makers on Murano. Personally I would not discount Murano - just a hunch.

An interesting vase but I have no idea who might have made it. Presumably there is a thin ring of wear around the edge of the base, entirely unscientific but does it look light or heavy to you?

Hey John, thanks for the look. There is absolutely no wear on the base at all. It's as if it's never been used...no mineral marks on the inside. I would have past it by is not for the pretty blue color I thought it was. I guess it makes no real difference , I really love the vase. Its fun....I can't say that about many of the things I own
