Question of Color? SCA! SCY? - 6/17/2008 11:51:34 AM    epgorge   Posts: 2526 Joined: 12/29/2006 From: USA Status: offline Here is a question for y'all to ponder. If sunlight (radiation) brings about solar colored amythest in bottles produced from manganese, does sunlight bring about solar colored yellow in those bottle produced with uranium, etc to bring about a yellow color? I have a Dr. Pierce Smart Weed that had yellow streaks through the neck, middle and base of the bottle a few years ago. Now the whole bottle appears to be turning deeper yellow. What say you?

The yellow in your pierce's bottle is likely some amber impurities. Not sure I can see a way UV light would change that. _____________________________ FREE Online Medicine Guide - http://www.antiquemedicines.com/MedicineNexus/Nexus.htm Web Site - http://antiquemedicines.com Email : mknapp@antiquemedicines.com (in reply to epgorge) Post #: 2

Never figured it out.

Selenium, also used to bleach the green tinge from glass, also exhibited a color change phenomenon when combined with iron oxide and ultraviolet rays. If left exposed, the glass would turn amber in color (pale goldy yellow).   I have seen many clear selenium based bottles that have a yellowish tint. I never tried exposing them to UV. < Message edited by GuntherHess -- 6/17/2008 1:28:55 PM > _____________________________ FREE Online Medicine Guide - http://www.antiquemedicines.com/MedicineNexus/Nexus.htm Web Site - http://antiquemedicines.com Email : mknapp@antiquemedicines.com (in reply to capsoda) Post #: 4

Now I was talking to my aunt and I asked her about a vase she has. It is red with silver leaves on it. Very beautiful, she said the red glass is made from pigeon blood, has anyone heard of this? She is almost 80 and was told this by her mother, who could have been pulling her leg? Whitefeather _____________________________ What a wonderful earth we have from Grandfather ...let us work at keeping it that way....or we can"t find the bottles..

During the 19th century, trace gold was the chosen additive as ferrous oxide tends to produce a variable red coloration. The glass clearing agent, manganese, which upon exposure to ultraviolet radiation (UVA) does, indeed, color clear glass amethystine (sun-colored amethyst, or SCA). the "wolf packs" of Germany (unterwasserboots), or U-boats, played havoc with Atlantic shipping during World War One, particularly when the United States entered the fray in early 1917. Hence, manganese importation was severely curtailed. I suspect there was a limited stockpile of manganese. But for all intensive purposes, "clear" glass turning purple on exposure to UVA dates from 1917 or earlier. Alternatively, selenium as a clearing agent for clearing glass was used. The element selenium, on exposure to UVA will turn the glass yellow in varying shades (depending on the concentration of the element to metal). By 1930, or thereabouts, glass manufacturers realized the error of their ways and discontinued the use of selenium altogether. Actual pigeon blood and its occasional consumption in any form is only good for fraternity initiation rites. Red Matthews, would you like to weigh in on this issue? < Message edited by cordilleran -- 1/14/2009 12:47:48 AM > _____________________________ A life unchallenged is a life unlived.

Wow that just blew my mind Cord! Sitting here enjoying my caffeine buzz I read that line and I kind of had an epileptic moment. Just stared at that and pondered it for what seemed an eternity.  A rather unenjoyable experience I don't wish to re-experience.

Its value increased making it less desirable to use as a glass cleaning agent. Though, I have never heard of the use of pigeon blood for red glass production, it sounds like a good one for urban legends. Ep (in reply to whitefeather) Post #: 9
