    Yup and its more cost effective. I mix it and use it the next day after it's cooled I didn't heat it the 1st time and it didn't dissolve. I also can't make gravy.........

    Is there such thing as powder developer and powder fixer? I want to be able to travel with all my negative processing equipment and powder would be much easier, but if fixer can't be obtained in powder form then I might as well keep on using HC 110 ...
    Are you traveling by Air, car, train, or ship? The reason I ask, if you are traveling by car or train and have room in your luggage you can take a small electronic scale and bulk chem to mix your own. Mix what you need then dump.

    This means that you cannot reliably mix up just a portion of the powder. You should mix up a whole package at a time.

    I think this is a myth. Think about it. Kodak does not dump the metol, HQ, and borax into each bag. It's mixed in a huge drum, I would wager, and then is put into packaging. So, right off the git go they are doing on a bigger scale what the home user would do, divving up a batch.

    sodium acetate, which, when mixed with water
    yielded acetic acid?
    Sodium acetate produces an alkaline solution;
    ph 9 or a little more. About that of borax.
    Likely a good substitute for the latter
    in some darkroom chemistry. Dan

    Use vinegar. KISS. If you have the chems available, citric acid or sodium sulphate work fine, too. I use the latter because I have it as a pool pH reducer, about $2/lb. About 1/4-1/2 tsp in a tray works great. Dump it when done.

    KISS

    More likely sodium BIsulfate. The sulfate is a near
    neutral salt. Bisulfate is quite acidic. Dan

    Yes, I stand corrected.
