    I've formulated 2.5 liters of two solutions D-85 (kodak lith developer). I
    don't find Paraformaldehyde and i've replaced it with around 200ml of
    acetone (82.5 mm x 2.5) but the solution DON'T WORK!

    For a test, i've mixed 4 parts of solution A with 1 part of solution B (no
    water) and i've make a strip test with 2 min, 4 min, 6 min, 8 min and 10
    min. exposure time. I've immersed the strip into solution and after *10*
    minutes the strip test was always white (no halo, no shadows)

    How can be happened?

    Sorry, have patience, a second question:

    What is life time of FX-37? My formulation have now 4 mounths.

    thanks to all and sorry for my english!

  4. Hard to say. You must remember that few brands of paper really "liths".
    Try with following: Fortezo, Maco Expo, Kentmere Art Classic. Another
    way: switch on Kodalith developer or Maco Lith dev. For example, Agfa
    MCC liths well in Maco Lith and it is always in stock from common
    dealers and cheaper than others. But if you are on the path: "wanna-brew
    myself-MY-OWN-stuff", I think that P. Gainer Vit C + Hydroquinone +
    Sodium Carbonate works fairly well as a lith developer without typical
    drawbacks of D85 and without poisonous matters like paraform. However
    take care about streakings and heavy and large spots with this formula,
    that is unstable. You can read more here:

    Dunno about ornanno S3 lith, but surely will work if they label it
    that-a-way. Sorry, can't help ya with D85, I'm not a chemiman.

  8. Why would you think acetone would substitute for paraformaldehyde?
    Why not just buy Kodak Litho Developer?

  10. Why not just buy Kodak Litho Developer?
    Try stores/companies that sell to printers, as in printing newspapers,
    printing menus, printing business forms .... these stores will all carry
    lith developer - many photo stores don't (heck, many photo stores
    around here don't even carry Dektol).

  12. If the original formula is with parafolmadehyde, then of course it doesn't
    work without it.

    NO! the original formula is with parafolmadehyde, but is specified that it
    can be replaced with ACETONE.

    "You may substitute 82.5 millilitres of acetone for the paraformaldehyde"
