D76 dev solution - questioning the container

    Hello all. Since most jugs made for storing chemistry are of a dense
    plastic material, I was wondering if a gallon milk jug could be a temporary
    fix? I am assuming it would be alright but one never knows unless they have
    the facts. Thanks in advance.

    D-76 (and many other developers) wants to be kept away from light and air. A
    milk container is a bad choice for long-term storage on both counts. A
    detergent container (heavier grade plastic) is better, but getting it
    completely clean can be difficult. Best is brown glass with a non-metallic
    cap.

    Additionally, it is not a good practice to store chemicals in containers
    that are commonly used for beverages, especially if children have access to
    the chemicals.

    Very good point. I remember coming home from grade school once, finding
    two quart bottles of luscious looking Cherry Kool aid on the kitchen
    counter. I took a good swig. It was Rit clothes dye. :)

    (Sorry, Mom!)

    But I had cherry red lips...

    OK, so Broadway it ain't, but it was fun...

    I've been keeping ID 11 (the same as D 76) in flexible but sturdy
    plastic containers for several years now. My 5 liters of ID 11 rarely
    last longer than 9 months. But during this time I never encountered
    any problems. I'm a zonesystem photographer, so I keep a strickt
    control on my chemicals.

  6. Many years ago I remember reading somewhere that brown glass bottles
    had an inherently more neutral pH than clear glass ones (somehow
    related to the chemistry of their manufacture) and thus could
    potentially alter the pH levels of photo chemistry--or whatever
    else--stored in them over longer periods of time.

    I was never able to confirm this and have occasionally wondered about
    it ever since. I use brown glass bottles for my photo
    chemistry--albeit not for reasons of pH. But if anyone knows the
    definitive answer to the question of whether this is true or not, I'd
    be much obliged.

    Thanks,
    Ken

  7. Oh, come on, give me a break: this is clearly in the realm of photo-folklore.
    Glass has no pH either way: possibly to a particle physicist, but not in any
    practical way to a photographer. I think this was made up by people who just
    like brown glass containers better than clear ones.

    "Oh, kewl, they keep the light out AND they're more expensive! They must be
    better."

    At Boston/Logan airport last Friday, I saw on a Delta departures/arrivals
    screen this Windows error dialog in front of the grid of flights:

    "At least one service failed to start..."

    I took a photo of it. I thought:

    "I'm glad I don't run Windows. I'm glad I'm not flying Delta today."

    Glass is made of silicon and oxygen. By the very definition of the term
    it can't have a pH. Acids or bases must have free H+ or OH- ions to
    have pH.

    HD or LD, what's the difference unless one is planning to
    boil the stuff. Find some nice bottled water bottles. Use the
    water for coffee, orange juice, or whatever. There is a large
    variety of sizes and shapes on market shelfs.

    I use chemistry one shot so here is what I would do. I'd put
    the ID11 stock solution into one liter bottles. One of those bottles
    would be dispensed into several smaller bottles. Each of those are
    to contain just what is needed for one roll, the few sheets,
    or whatever is to be processed.
    Use one shot and toss. Keep the other bottles sealed
    untill needed. Dan

    This is the first time I've heard this. Brown is supposed
    to prevent ultra-violet light from affecting the content of
    the bottle.
    Now, carbonates will dissolve glass, so, if you keep
    strong carbonate solutions in glass for long enough it will
    become etched. This is of absolutely no practical
    significance for photo chemicals but is interesting to know.

  11. Sure it is, Richard. Try storing a Carbonate stock solution in glass.
    It will eat through the bottle wall in a year or more and the fluid
    will flood out.

    I know, I did this, and that's what happened.

    Keep ypur pH down when storing in glass, folks.

    I've been using an old Jack Daniel's bottle to store my hypo-clearing agent,
    and an old Gatorade bottle to store fix. How do these chemicals compare to
    developers w.r.t. reactions to air and light? I haven't stored them in a
    light-tight cupboard. I've been using hypo-clearing as one-shot, but the
    fix I reuse and I haven't been great about doing regular tests using the
    film leader.

    For developing, I've recently started mixing HC-110 directly from
    concentrate thus I don't have a problem storing this.

  13. Sounds fine to me... If you need help adding another Jack Daniels bottle to
    your collection, give me a holler... Depending on how long you keep fixer
    you may want to consider a glass bottle for it , also...

    What about potassium and sodium? All you've mentioned is quartz. Dan
