Talk:Uranium glass
From Wikipedia, the free encyclopedia
Hallgrímur: It wasn't a typo. In the previous paragraph, I specifically talk about the 1840s, then in this paragraph, I say "the end of the century". Keith D. Tyler ¶ [AMA]
Trinitite is also light green; since actinides are so similar, chemically, should we discuss that material in this article?--Joel 23:30, 15 July 2005 (UTC)
- I'd say not. I'm pretty sure that trinitite's colour isn't down to actinides, but (like green bottles) to reduced iron. Check out this PDF paper which contains an analysis. Tearlach 04:23, 26 July 2005 (UTC)
Riedel confirmed. It's a glassmaking dynasty: see history page at www.riedel.com. The uranium glass one would be Josef Riedel the Elder of Polaun (the German name for Dolni Polubny). Tearlach 18:42, 26 July 2005 (UTC)

[edit] Old images -- ????
What the hell? The Image:Vaseline Glasses.jpg did work once, it was uploaded to the Commons after I made a request in Picture Requests. Where on earth did it go to? - Keith D. Tyler ¶ 20:32, July 26, 2005 (UTC)
I dont understand why the image
was deleted, I can see it very good. I downloaded 4 images, if anyone want to use it in the article, its possible I dont have enough of experiences of it /sorry for mt english :)/

[edit] Please clarify the origin of "vaseline glass"
Two different reasons are given for the name "vaseline glass", namely:
- "changing from its normal transparent yellow or yellow-green with increasing opacity to, ultimately, opaque white. This material, technically a glass-ceramic, inspired the name "vaseline glass" due to its similar appearance to petroleum jelly."
and:
- "Vaseline glass gets its name from the original formula for Vaseline Petroleum Jelly which was yellow-green much like the color of antifreeze."
These two versions are not consistent, could someone with experience in this field plase clarify? --Paiconos 20:47, 21 April 2006 (UTC)
[edit] What is considered an EXCEPTIIONALLY large collection?
What is considered a LARGE collection? reffering to "However, the radioactivity of the glass is widely considered to be negligible and not harmful, although it is still recommended that exceptionally large collections be kept behind leaded glass." Because I have a neighbor who collects these peices and he has like 50-60 peices ranging from cake containers to punch bowls, Im wondering if his collection should be behind leaded glass....

I'm kind of wondering about the validity of that statement. Our article on uranium states that uranium decays by releasing alpha particles, which "are easily absorbed by materials and can travel only a few centimeters in air. They can be absorbed by tissue paper or the outer layers of human skin (about 40 micrometres, equivalent to a few cells deep) and so are not generally dangerous to life unless the source is ingested or inhaled." I don't think leaded glass would be necessary. I just wouldn't, say, eat the cake containers or punch bowls themselves. The lead glass article itself says that lead glass is used to stop x-rays; alpha particles are nothing like x-rays. TomTheHand 17:49, 19 March 2007 (UTC)

[edit] Earliest use?
I arrived on this page from the article on uranium. There, a source is cited as saying that uranium was used in glass in oxide form as early as 79 AD. As the source is a government website, I believe it is trustworthy, but I will entrust that conclusion to you guys. 69.246.150.153 22:04, 21 March 2007 (UTC)
- I don't have JSTOR access to the full paper, but it seems to check out: Google Books finds the source of this statement to be The Earliest Known Use of a Material Containing Uranium by Earle R. Caley, Isis, Vol. 38, No. 3/4 (Feb., 1948). [3] I've added some detail on this and other early use, partially from already sourced material from Uranium. Tearlach 20:29, 25 March 2007 (UTC)
