\"\"<\/a>I picked up a set of five (one was chipped) of these stems when I was in the U.S. earlier in the year.\u00a0 I figures, and I was right, that I would have difficulty identifying them as their shape is fairly common I think.<\/p>\n

I am guessing that these are a small wine at 5 1\/2 inches tall with openings of 2 1\/2 inches.\u00a0 There is a narrow optic.\"\"<\/a><\/p>\n

I do not really know the difference between uranium and vaseline glass.\u00a0 The two terms see to be used interchangeably by some.\u00a0 This is now the Encyclopedia of Glass<\/em> by Mark Picvet defines each:<\/p>\n

“Uranium Glass – A brilliant fluorescent yellowish-green glass produced by the addition of uranium oxide.\u00a0 Due to the nature of the metallic element uranium, uranium glass is mildly radioactive (but not harmful) and glows brightly under a black light.\u00a0 It was first made in the 1830s in Germany.”<\/p>\n

“Vaseline Glass – Glass made with a small amount of uranium oxide (usually 1% or 2%) that imparts a light greenish-yellow color (a greasy appearance like vaseline).\u00a0 Vaseline glass usually glows under a black light.\u00a0 Vaseline-like glass was first made by the Romans; however, it was not used in glass production in any quantity until the mid-nineteenth century.\u00a0 The term “Vaseline” was not used until about 1937.\u00a0 Note that the English usually refer to Vaseline glass as “Lemonescent” which has also been called canary, yellow, uranium, topaz, magic, Canaria, |Chameleon, Anna Yellow, Annagrun, and Lenora Green.”<\/p>\n

I am guessing that my stems are Vaseline.\u00a0 Any hints as to their provenance will be appreciated!<\/p>\n
