    Old Chemistry

    Hello Everyone,

    Just a quick question. I think I no the answer, but thought I would get a second (or several) opinions. I have an old bag of Dektol with and expiration date of July 2007 and a bag of Kodak Fixer with an expiration date of April 2007. These have been stored in the dark in temperatures that have not exceded 85 F (power outage during a hurricane). Is the consensus that I should dispose of this or might it still be safe to use? I don't think I want to try it, but the cheapskate in me says to try it.

    Thanks in advance,
    Aubrey

    old bags of Dektol, Kodak fixer

    I've used both, equally old, with excellent results.

    2007 isn't very old. 1977 is getting there. If the powder isn't caked in the bag or discoloured, and the Dektol mixes up to a vary pale beige or light tan, it should be good. The fixer should be white powder and mix up water white.

    It would be simple enough to make up a small amount of each next time you are printing. Test the developer with small strip of properly exposed paper and the fixer with a film leader for clearing time. This is the sort of test I always do with home brew developers and I keep a pot of film leaders in the darkroom to test clearing time,
