Glass Chatroom Board

Hello everyone and thanks Jesse for the very nice introduction! 🙂 As he mentioned, I have 2 pr of candlesticks that I'm having trouble properly identifying and describing for my Etsy shop. The first pair are blue, and flouresce a chartreuse color under blacklight (stronger glow the closer to the light; I have a 60w bulb inside a gooseneck lamp, mainly for checking teacups up till now!). I have no idea whether these are uranium glass, Depression glass, or what... totally clueless. Here are the specs:
Height: 7 7/8"
Diameter of base: 4 1/8" outside edge to outside edge
Candlecup dia: 1" Depth of candlecup: 1"
Overall dia of top 2 1/4" (thus, the lip is 5/8" wide from candlecup to outer edge)
Diameter of the balls on the stem: 7/8"
Base is "open" and about 3/4" deep (wasn't sure how best to measure this)
Seams can be felt all the way from the underside of the top lip to the bottom of the base, although they feel the sharpest along the stem. The top of the lip rim is smooth; I cannot feel a seam there but I can both see and feel it underneath. If I run my finger along the outer edge of the top lip, I can feel a slight gentle bump where the seam edge begins. Looking closely at the bases I can see a very faint ripple effect (in other words it is not perfectly clear, as a piece of window glass would be) and there are a few tiny bubbles as well; some individual and others in a line, approximately 1/2" long. Both bases exhibit both kinds of bubbles.

Here are the links to pics that I have on Photobucket. I would describe the color as slightly lighter than what I think of as cobalt blue, but not as light a as the ewer pictured at left on the chatroom board image. IMHO this is more of an ultramarine blue than a dark cobalt.

There are, naturally, no markings, numbers, or anything else that would help identify who made these or when. That would be way too easy. 🙂

Please let me know if there are other measurements I should take, or things I should check for. Many many thanks!
