    Or as someone said of swimming at (I think) Margate, "You don't swim, you just go through the motions."

    one could perhaps try Real Salt, or Sea Salt. Instant sea water!

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    [QUOTE=john_s;400209]
    "A lot that has been written on the subject dates
    from when hardening fixers were used. Now that
    hardening fixer is generally not used, that is not
    such an issue,..."

    Not "...such an issue..." is the ph of the hca.

    "...although the pH of the wash aid is still considered
    worth keeping at around the level of the Kodak product."

    The Kodak HCA's ph; perhaps 7 or a fraction more?
    Some one with a ph meter and the Kodak product?
    Were a pole taken I believe we would find that the
    Kodak ph is favored more so by those not eager
    to use alkaline fixers.

    Your Quoteing Mr. Knoppow:

    "Sulfite seems to have a specific action
    which carbonates and borates do not have."

    Not really saying anything. Some might infer that
    sulfite Only has what it takes.


    "There were extensive experiments made at Kodak Labs
    testing all sorts of salts."

    Likely Mr. Knoppow is refering to studies conducted in
    1956 by Crabtree and Henn then published by Kodak;
    Communication No. 1790.

    "The measured level of thiosulfate in an emulsion was
    reduced much more quickly after the sulfite bath than
    after bathing in any ..."

    Mr. Knoppow: <end quote>

    "I have not read the original articles, but I trust Richard
    K enough to accept his summary."

    His summary? All he has said at end is that sulfite is
    quicker. Nothing of it's short in use life span. Carbonates,
    borates, and sulfates though do work and, I'd add, keep
    on working. Or did work. Or work better. Has any research
    been done since fifty years ago. Emulsions have
    changed since the 1950s. Dan

    Just to add something to this ancient thread: According to Ron Mowrey sodium sulfate reduces swelling in gelatin. This means if enough sulfite is converted to sulfate you may have to wash forever ...

    You could do what some non-siver printers use... drop or two of "thymol".

    Now... I'm not sure if the thymol is as 'anti-bacterial' as it is anti-fungal'.. I'd have to go do some searching
    in my 'old' file cabiniet.

    I am glad this old thread has been revived... My photo dealer no longer stocks Hypoclear or other wash aids.

    Cheers,
    Tom

    Wikipedia claims it's both ...
