    Ferric Oxalate

    I was wondering whether members using this chemical for their alt.process printing make it or buy it in for the sheer convenience and reliability of purity.

    I was planning to buy it when I move on from doing Vandyke Browns, but I'm not ready to move on yet. However 'buying it' doesn't seem to be an easy option in the UK! Do you have a supplier in mind; IIRC I couldn't find one.

    It is some time since I was in alternative process mode but for whats it's worth it was always used ready made. I had a very sympathetic chemist at the time so no problems in getting it fresh. You will know that the shelf life is quite limited about three months, so it is always necessary to make a test strip. It should be mixed at least 12 hour before use. Another very friendly chemist that you probably know of is, Dr Mike Ware at www.mikeware.demon.co.uk. Best wishes.

    I just tried my first alternative process print last weekend and it worked great. I did a Ziatype. I bought the kit from Bostick & Sullivan in NM. (I know, not UK, but that's where I got it nevertheless).

    Diane, are you going to post it into the gallery ? Glad you achieved a good result.

    [QUOTE=Stan. L-B] so no problems in getting it fresh.

    It is possible to make it yourself but I suspect that unless you want to put yourself to the test, ready made would be more convenient and reliable. I was just wondering whether many people bothered to make it. I know that Mike Ware has evolved some "safer" systems so perhaps I shall read his articles to see what chemicals he uses.

    Ferric Oxalate

    The ferric oxalate lasts a long time in powder form. After it's mixed it starts to degrade, if that's the right word to use, but even then it lasts a good while if kept in a cool dark place. I purchase the dry powder and mix a small amount a day or two before I plan on printing. Never had a problem with quality of ferric oxalate purchased from Bostick&Sullivan.

    I think it's $8 for 25mL of Ferric Oxalate from Bostick & Sullivan in a dry powder. This dry powder comes in a amber glass bottle; just add water and a dropper and you're ready to go! I'm lazy so I'll probably just order my Ferric in 25 or 50mL amounts (depending on how much time I have to print in ~2 months) so that I don't have to measure anything out.
    Let's see what I've got in the magic trash can for Mateo!

    Roy: in "Making Kallitypes" by Dick Stevens, he recommends making your own and I asked Sandy King about that and he recommended just mixing your own and using it within a couple of months. Now I mix up one half of the FO instead a full batch so it never gets too old.

    I assume then, that you buy it in. Do you get it from B&S ?
