    SilverGrain Clear Fix

    I'm considering replacing Kodak's Rapid Fix with SilverGrain Clear Fix in a community darkroom. The Clear Fix PH is 7.7. Is the PH more alkaline than Ilford's Rapid Fix? Does anyone have any comments on using this new fix with a water stop in a community darkroom environment?

    Richard, PM your question to Ryuji Suzuki. Clear Fix may be one of his formulations.

    I've used Silvergrain Fix before, but mainly when doing lith prints since this more alkaline fix doesn't bleach the lith prints like rapid fix tends to do. It worked very well for me, but I've only used it in small amounts for my one person darkroom. I don't know of the benefits/detriments of using it in a community darkroom.

    I prefer TF-4. It is a known quantity that uses established chemistry suggested by Grant Haist.

    I use TF-4 in my own darkroom and fixing film at the community darkroom. I wish to establish sound practice with new students; therefore I lean towards using product directions to avoid student confusion. Clear Fix allows either a water or acid bath. I'm not sure if it is much different than Ilford's Rapid Fix.

    Why not just use TF-4? A controversial discussion on the photo net forum indicated TF-4 can survive the acid stop but the product label only recommends a water stop. I wish to use water for film and weak acid stop for paper due to workflow.

    Anyone have any product info or suggestions.

    The cloudy appearance of TF-4 is due to a huge load of buffer. This is there to allow it to survive all possible process conditions including use of an acid stop.

    This is good enough for me.

    I have kept it in perfect condition for over a year.

    Are you using an acid stop bath with TF-4?

    Ryuji is definitely the man to contact. Clear Fix is his creation. I've only used it occasionally but I've liked what I got. He's one of the nicest guys out there as well, always willing to share info and help out. Try it.

    I believe a good case can be made for the use of
    an acid stop IF the fixer is also acid and must be
    maintained so.

    If a fixer need not be maintained in an acid condition
    then I've doubts a stop of any sort is required. I know
    that developer is needed. I know that fixer is needed.
    I know why each of the two is needed. Save for the
    case of an acid fix I don't know why a stop of any
    sort is needed. Dan
