Re: Anybody experimented with Argyrotypes?
I used negatives, that were a little contrasty for SG, but not very much. As the other says, the paper choice is crucial for this proces (contrast depends of paper too). I sometimes got perfect image out of water but after drying they were ruined at drying (irregular spots ...). But even not perfect ones are sometimes quite interesting. I have one which is quite "dreamy" (without contrast, faded ..., I showed it at my exhibiton) but very suitable for the image (but that was merely a luck), quite a lot ended in a bin.

You need pretty contrasty negatives for Argyrotype. Much more contrasty than what you'd need for silver gelatin. If your negatives are exposed/developed for s/g printing, I'm afraid you won't be able to get nice contrasty/punchy Argyrotypes. (AFAIK, there's some contrast control with the chemistry but I'm not sure if that will suit negatives optimized for s/g printing.) I don't think they're necessarily more stable than any other process giving colloidal silver image on plain paper - as long as the images are correctly processed/thoroughly cleared. Especially so when you choose to tone your images with noble metals. I had good results with Bergger COT 320 paper (the only paper I had used for making Argyrotypes). As a rule of thumb, any paper that doesn't give problems with New Cyanotype is also good for Argyrotypes. Search the web / list archives for paper information. If you extremely value image stability (and need the extra protection) then you should definitely tone your Argyrotypes (or Vandykes/Kallitypes/Salt Prints) with gold, platinum or palladium. But be aware that toning for extra longevity comes with the price of changing the original color of the image.

I have some negatives in black and white which I want to use for an exhibition using this technique (Argyrotype). I've read a couple of books which suggest that this process is more stable than a couple of other processes I was considering. Since you've experimented with this process are there any particular paper types (brands?) which you'd recommed? I will have to mix the chemicals myself since they're not available pre-made here in Colombia. I have some experience with the Bichromate Gum process from when I worked in Arte 2 Grafico (an artisanal/crafts workshop - http://artedos.com/ ) but this is the first time I'm experimenting with this particular process and the stability/longevity of the images to be used for the exhibition is very important. Any other advice would be very welcome and greatly appreciated. Sincerely, Fernando Cruz -- Fotografía y diseño.

What exactly do you want to know? The first thing to mention is that it's a very picky process when it comes to paper choices; you have to use the best and purest papers. Also, it's better to tone the image in gold before fixing, if you value longevity that is; colloidal silver in paper is pretty vulnerable... And the color + darkness is beautiful that way. (Pt or Pd toning also is possible, but, personally, I got best results with gold.) It's pretty easy to mix the solution - definitely more complex than Vandykes (if you have to compound silver oxide yourself) but not a big deal. Mix a volume enough for a couple of months (not longer than 5-6 months), the solution will deteriorate and silver out as time passes.
