    I hope not the Hatfields vs. McCoys...
    I do use a digital device in my photographic pursuits when necessary.
    When someone rags on me for using film, I use a middle digit, upraised.

    The pH produced by sodium tetraborate (borax) and sodium metaborate (Kodalk) are quite different and one cannot be substituted for the other. Borax is a mild alkali while sodium metaborate is almost a alkaline as sodium carbonate. If the FDC says that they are interchangeable then this is another error in a poorly edited book. Borate chemistry is rather complex and the naming can be quite confusing.

    Years ago I contacted US Borax about the purity of Twenty Mule Team borax. It is more than pure enough for photo purposes. The principle impurity is a very small amount of sodium chloride.

    I'd heard the dish-soap thing before from someone working in a photo store. He told me only use it in a "pinch" (if you really really have to and can't get the correct stuff), and that with proper technique surfactant probably isn't even needed.
    not so sure i would recommend that at all

    nope i would agree with you 100% ..
    but you used photoflo ( which i agreed with you 100% ) and
    borax ( which can be used successfully ) ..

    my point is that there are things that can be used with no ill affect
    if they are not photo grade or pharma grade or just sold off the shelf
    at abc-mart.

    but i do agree with you .. there are a lot of foolish people who do foolish things.

    thanks gerald

    i was going by what is quoted here:
    http://www.largeformatphotography.in...1-Borax-Kodalk

    that in some instances it can be a useful substitute.
    i don't have any borax, or kodalk, only metabrate ..
    so i really can't say if it works or is absolutely foolhardy.

    i haven't made divided d-23 yet ( which is what i got the metaborate for in the first place )
    so i can't even make a comparison between the original recipe and the one Anchell & Troop's Film Developing Cookbook
    suggest can be done instead with borax ...

    but i agree with a lot of what you ( and steve ) have said
    that people do foolish things to save a few cents, and often times in the end it is a waste of time and money and energy.
