    Adding other chemicals to combine their special benefits is okay for me, as long as the developer produces better results.

    David, you are right, but as I said in the beginning, one of the interesting aspects of "Java" developers is that they are not toxic, and dumping used devloper into the sink is not a problem. With Pyro developers this is very different: they are pretty toxic, and at least here in Europe it is off limits handling it like a harmless fluid.
    When you combine Muriatic Acid (AKA Hydrochloric Acid) with Sodium Hydroxide you end up with Sodium Chloride, water, etc., etc. (Kinda like Microdol-X).

    And see the current MSDS for Edwal FG-7.

    Simply because it is staining, but not toxic, and the results I have seen so far from Nescafé-and-Folgers homebrew stuff are quite impressive for such a simple recipe. With some experimenting and good scientific knowledge of photo chemicals it might become an excellent developer.

    i use caffenol C all the time,
    it works well for my fun in the darkroom ...
    i just make sure to get gut rot instant coffee.
    the vit. c is the expensive stuff ..
    i get mine at whole paycheck,
    since we don't have a trader joe's around here

    i do cheat a little bit ... sometimes i add some
    spent print developer or some straight print developer
    to boost the contrast a tiny bit. i usually add about "a splash"
    not sure exactly what that measure is exactly, seeing
    my coffee is " a big dump",
    laundry det. is "a medium dump" and
    vit c is "a little dump"

    (i stopped using true "international measurements" a while back )

    YMMV

    im empty, good luck

    John, for ascorbic acid try this place, http://store.allhealthtrends.com/pgi...cid,2,157,=,AA, relatively cheap and works well in my Caff+C recipe. I'm much more precise in measuring though, I use the pour and count method. Very precise.

    What does this developer do that a real developer couldn't do better?

    Caffeic acid is a close cousin of catechol
    So a pyro developer (commercial) will work more or less the same

    Adding vitC increases the activity/shadow detail and lowers the stain
    it if is cheating... so what?

    I really think commercial versions would be no fun

    No problem John.
    I'm not sure how much it is at "whole paycheck" but I'd guess twice the price.:rolleyes:
