That doesn't sound right at all. I have some of the same stuff that is quite old and recently used it and it worked fine. I would say there must be some source of contamination with yours.

Hi again,I've run into some unexpected problems toning with KRST. I've been doing some tests and comparisons and wanted to check out the Kentmere papers. I got what we had in Montreal, "finegrain" and "warmtone", both semimatte VC papers in 8x10 size. I wanted to compare it's toning properties with Agfa MultiClassic. I had a half full bottle of KRST which has been on the shelf for close to a year. I diluted the selenium 1:9 in distilled water as is my habit. By the time I had the second sheet of Kentmere in the toner, the toner started turning brown and by the fifth sheet, the toner looked like liquid fudge; impossible to see the image in the tray.I had done the prerequisite washing, 5 min in Hypo Clear, then a 40 min wash in running water, the selenium was mixed with distilled water, no other additives. I went to the photo store today to get a fresh bottle of KRST and asked the clerk about the phenomenon of the selenium going brown. he told me that if it had been sitting on the shelf for close to a year, half full, then it went bad. Is this a reasonable explanation, that the toner went bad, oxidation because only half full????With the fresh bottle of KRST and using some left over prints from yesterday, I proceeded to tone them, same protocol as before. By the second sheet, the selenium started getting a brown hue to it. I find this week's experience with KRST rather odd because I have never had it go brown on me, not especially with a fresh bottle of KRST.I'm trying to figure out what went wrong and nothing comes up.Several questions: what is the shelf life of KRST? ... I checked the Kodak web site but no information on that score. Is the Selenium dilution supposed to change color after only several sheets have been toned in it??? And turning brown???If anybody has any ideas, comments, questions or other observations, they are welcome. I sort of miffed and puzzled by this experience and would like to get to the bottom of it.Cheers, bogdan-- ________________________________________________________________Bogdan Karasek Montréal, Québec bogdan@xxxxxxxxxxxxxxx Canada www.bogdanphoto.com "I bear witness" ________________________________________________________________======================================================================= ====================================== To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
