    Hey Ken-

    You mentioned in a thread you had a book that explained this process.
    I contacted Kodak this morning and they have two books that appear to
    be related to the book you have (if not one of them being the book you
    have):

    Photographic Retouching
    Publisher: Sterling; (March 1998)
    ASIN: 087985474X
    (out of print but available through amazon probably)


    Conversation of Photographs
    Publisher: Silver Pixel; (1985)
    ASIN: 0879853522
    (in print)


    I have tried Acetone which just curls the negative as it dissolves the
    plastic. The image remains on the plastic so contrary to a few
    threads it doesn't appear to work. It takes about 5 minutes to
    completely *destroy* a negative, though :) (I have tried both CN/BW
    negs).

    Thanks alot!


    Cheers,

    Dear Friend,

    You said that you used acetone. Do you know the health risks associated with
    it? If you must use it, be sure that it is exhausted rapidly and that you
    guard against skin absorption. The laboratory where I worked banned it (for
    good reason).

  3. Did you ever read the book, "The DOSE makes the Poison" second edition,
    by M. Alice Ottoboni, Ph.D? She was staff toxicologist for the
    California State Department of Health for 20 years and knows what she is
    talking about. She does not specifically discuss acetone, but her
    guidance reduces the need to be hysterically fearful of chemicals even
    though they can be hazardous.

    I do know that the lab next to mine used all kinds of nifty chemicals,
    including acetone, rhodamine 6-G, absolute alcohol, ...
    One right downstairs used arsine, phosphine, and hydrogen selenide. They
    never had any problems with things like that, and they are certainly
    more toxic than acetone (in fact, they are 200x more toxic than hydrogen
    cyanide). Remember, even carbon dioxide is toxic in sufficiently high
    doses, yet people drink it in soft drinks and Champagne.

    You should certainly use care with any chemical you work with, but even
    those nifty gasses above, toxic at 0.05ppm can be worked with safely.

    Yeah they're probably pretty bad. I wore gloves and an
    aspirator..can't do much else...

    Thanks for the tip, though...I know its sketchy stuff..

    flipper babies and whatnot..

    Be careful with that poisonous substance, water.
    If one drinks some 5L of it at once, there's a real life risk.

    Jorge,

    Does water give you cancer? Seriously. These comments about the toxicity
    of water and carbon dioxide are reqrettably specious and may serve to
    trivialize the long term risk to someone unaware of chemical hazards.

    My father worked for a very safety aware company, DuPont. They were clearly
    a leader in safety long before current workplace safety laws were enacted.
    Yet nearly every man he could recall developed cancer after retirement. He
    too died of cancer. I recall that they were casual about acetone and
    other solvents such as trichorethylene. They even made their own waterproof
    glue using neoprene and acetone. They paid a terrible price in the very
    long run.

    In my engineering career, I made it a point to know about the solvents in
    use and abolished a serious overuse of trichlorethylene that was harming our
    lab crew.

    One thing is for sure, acetone is not going to improve your health in any
    circumstance. Perhaps we can agree on that and caution people considering
    their use about less than apparent risks.

    Glad that you showed the wisdom to use gloves and aspirator.

    Two details that you may already know. First, be sure the gloves are not
    porous to acetone. Some pass certain solvents and are really for water etc.
    Also, be sure that the aspirator cartridge was rated to remove acetone if
    you use it again. I believe that it should have activated carbon. I ran in
    to one case where a chap was using a dust cartridge and surely wasn't
    protected from solvent fumes.

    Cheers.

    A facetious but somewhat diametric comparison, however, since too much
    water is dangerous for the opposite reasons associated with toxicity.

    Yada, yada, yada this poison nonsense... to a point. My grandfather
    started smoking at 14 and flat-out died 85 years later. Why look what
    cigars did to George Burns!

    What, exactly, are the risks of acetone. I use about three quarts a year
    for body prep, degreasing small parts, disk brakes.

    With my b&w neg, HP5+, the base turned gelatinous and clear and the emulsion
    pulled clean away from it, and then curled up. I uncurled the negative in
    the acetone using hemostats (I messed up the neg a little, but that wasn't
    my concern at that point). The negative image looked fine on the emulsion,
    albeit, I couldn't hold it up to the light, and the light wasn't that great,
    as I conducted the experiment on my back porch at night. I was using a
    bright white bowl, though, and could clearly see the image. It was an image
    from the end of a roll that had suffered from a little light leak.

    When I took the emulsion out of the acetone it got stuck to itself. I
    opened it back up, and it started to dry and buckle and get a white film on
    part of it, which I suspect was residue from the base. Within a few minutes
    the images was unusable, though still clearly visible on the tissue-like
    rectangle of emulsion I'd extracted.

    Fish do. But AFAIK, we are not like them.
    Seriosly, if you drink a lot of water at once, you may drown. It's not
    the same as not been able to breathe (asphyxia).

    I fully appereciate your point, but as Jean-David posted, one have to
    take in account how much of it.
    Acetone has been used for decades to remove nail's enamel. Is there some
    data that shows persons that worked at hairdressers to have cancer rate
    above the average?
    If so, I've never heard about it.

  15. In general, unless someone asks for advice one should
    assume the other party knows what they are doing.
    Do people drown in acetone? Hyponatremia, anyone?
    This has got to be a new definition of safety. High explosives,
    firearms, tetra-ethyl lead, freon, ... the list just goes on and
    on ... Just whose safety are we talking about here?
    You exhale the stuff. If you didn't have acetone, an average 10 um in
    your blood, you would be ill. Go on a low carb diet and the EPA
    will come shut you down for unsafe emissions (insert ob smiley face
    here). Got any females in the family? -- ask them about their nails.
    Doesn't look like it, does it?
    Go ahead. I don't think you will make friends or
    influence people, though. Preaching is best done
    in church.

    Hold on here. I dated a prety woman (pictures available) who had acetone
    breath and I thought she was a secret drinker. Broke up. Ten years later,
    she was a blimp.

    You won't drown. But something else (chemical) will happen you
    apparently know not what...

    Its all a mater of function over emotion. Just like women, there is always a
    raft of information from some other party (busy body), none of it ever very
    encouraging or useful but if it works you use it. Carbon monoxide CO
    produced by the gallon by most of us. Not much use but the factory it's
    produced in is, so we go right on using it.

    huh.
