>> Fernando, I did. What exactly do you want to know?
>> The first thing to mention is that it's a very picky process when it
>> 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.
