Re: Source for Uranium Nitrate
Check this: http://www.alternativephotography.com/forums/phpBB2/viewtopic.php?p=1240&sid=a88b7acc1ec3b1c729418c5adfa3aa8b/ The actual source is listed as http://www.americanelements.com/ I have about five grams of the stuff from years ago...but I'm not giving it away. ;^) Bill Crawford (Keepers of Light) says the colors in uranium toned pt/pd prints may be fugitive. It is neat that you can get different color simply by clearing for varying times.
