In the USA, the most common definition of vaseline glass is a yellow green (transparent) glass that contains uranium dioxide as it's only colorant. Green glass that glows has an additional ingredient (ferrous oxide, common name, rust), so that makes it something else. on ebay, people will list things as 'vaseline glass' that glow, even if it is green, just because more people will look at the item. It is getting to the point that so many are doing it, it may eventually change the common definition! In Germany, anything that contains uranium dioxide (no matter what color) is called uranium glass (uranglas, in the German language). In Australia, anything with an opalescent rim (even blue opalescent pearline glass by Davidson) is called vaseline glass. It just depends where you live. Yes, it can be confusing. When people insist what they have is vaseline glass (and it is not in my definition), I don't argue, I just tell them if they own it, they can call it anything they want to!
Now, in regards to your particular piece, the Yankees will call that translucent color ORALINE, and clear yellow-green glass (even if treated with a satin finish, or carnival glass over the top of the base glass, etc) is called vaseline. In France, if it has uranium dioxide in it, and it glows a neon green under a blacklight, it is ORALINE. no differentiation is made.
When I do a search for this glass on french ebay, I use ORALINE. When I am searching german ebay, I use URANGLAS. When I search ebay.uk, i type in PRIMROSE, URANIUM, VASELINE, and if ANY of the three words show up, I take a look at it. PRIMROSE, of course, is the key word in PRIMROSE PEARLINE, the yellow opalescent glass made by Davidson and copied by others. that particular glass is a big favorite of vaseline glass collectors in the USA. So is vaseline glass made by Webb, John Walsh Walsh, Richardson, and Stevens & Williams.
If you want to see some REALLY WOWZER vaseline glass, try this art glass page I put together. No, I don't own all of this (about 5 or 6 pieces in the photo grouping are mine). click on any photo for a larger view.
http://www.vaselineglass.org/artglass.html Some of this glass only has some of the trim as vaseline glass, but there is vaseline glass (whole or in part) in every piece shown).
Another page that shows some special glass is one where every piece does belong to me. Each photo can be clicked for a larger photo, that also shows a blacklit photo:
