    Lith print with normal developer

    Hello,
    there're a lot of specialized lith developer; lith process start when a hydroquinone developer is used. Anyone has experience diluting Ilford Multigrade developer to have a lith print? normally it is diluted at 1+9 but maybe with high dilution you can have lith print. Furthermore i red that old and exausted developer is better to have lith print.
    Any experience?

    thanks
    Paolo

    ps. the same question for tetenal Eukobrom developer...

    A lith developer has a high PH, often around 11. It is (usually) low in bromide, and high in hydroquinone compared to sulphite content. According to Tim Rudman, it is possible to simulate an infectious development process with a dilute MG dev, but you need to add a hydroxide solution to raise the PH first.

    Yep.....that said, I was able to get sodium hydroxide from the hardware store as drain cleaner (highly caustic, use gloves, need to read lable to get right stuff). If you do use NaOH, make sure you add it slowly to the developer stirring. It heats up as it dissolves. Anyway, you'll need ph strips or a ph meter (I have a cheap one for aquariums). I'd just get the real lith developer. Life is short. Also, diluting regular developer isn't the same as diluting lith developer. You'd need to experiment with the dilution. Sounds like an interesting experiment.

    maybe with Na2CO3 (Sodium carbonate) would be less dangerous...and it could be found as easily as sodium hidroxide, ?

    Sodium carbonate is not going to provide the high pH needed. You need sodium hydroxide. Be careful some drain cleaners contain aluminum turnings or other chemicals. The aluminum generates gas and provides agitation in the drain. Buy plain lye such as Red Devil brand.

    You can look at this recipe, http://www.apug.org/forums/forum222/...developer.html , if you would like to mix your own lith developer.

    hi eskimo,
    Moersch in Germany sells f.ex. Easylith and at a very reasonable price:
