This is my first posting to ANY list, so please please bear
with me if I err in any way.
I am guessing here, but if Adam used tap water instead of
distilled water, any chlorides in the tap water will result in
a milky silver nitrate solution, due to the formation of silver
chloride. My source (Robinson and Abney, "The Art and Practice
of Silver Printing", 1881) recommends that if this is the case,
it must be filtered out, although I do not know what that means.
Now a question I have about a silver nitrate solution is
that the stuff I have read recommends that the solution be heated
(about 100 degrees F) before use. Any comments on the necessity
of this?
