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
>> 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.
>>
>> Regards,

Loris.
