    So my can of Dektol on the chemical shelf is not just for decoration?

    I was given a partial carton of paper/foil laminate bags of Dektol when a company I worked for stopped using the "Headliner". This was in 1984, they were old at the time and I still have a few of these bags left. When it's time to make up a batch I occasionally reach for one of the old bags and mix it up. For years the bags were good as new but lately about half the bags mix up dark brown like a rich cup of coffee. Then I dump it and reach for a fresh bag.

    But if it's caramel-colored, I'll use it.

    in the days when Kodak developer come in Cans, the manuals listed most of them as having a life of "Infinite in package" In spite of having a date on them, the Freestyle chemicals I have in the drawer are on Millitary style foil envelopes and I am crossing my fingers that they will still be good when I use them.

    Yesterday I just mixed up a can of 2 part D76 that I think was from the late 40s early 50s and used it to develop a couple sheets of Fomapan 100. It worked great. You'd never know it was as old as it was. It had a little 2" tall cardboard oatmeal box style package above the off white crystals. The can opened with one of those twist keys that was attached to the bottom of the can.
