Question of Color? SCA! SCY? - 6/17/2008 11:51:34 AM    epgorge Posts: 2410 Joined: 12/29/2006 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. _____________________________ Looking for Frederick Maryland and Dr Fahrney Bottles 2008 Medicine Bottle Price Guide on CDROM http://www.mattsoldhouse.com/MC/bottles/BottleBook2008.htm email http://www.mattsoldhouse.com/MC/bottles/email.jpg (in reply to epgorge) Post #: 2

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 > _____________________________ Looking for Frederick Maryland and Dr Fahrney Bottles 2008 Medicine Bottle Price Guide on CDROM http://www.mattsoldhouse.com/MC/bottles/BottleBook2008.htm email http://www.mattsoldhouse.com/MC/bottles/email.jpg (in reply to capsoda) Post #: 4
