RE: Purity & Prices
Eric,
I have very little experience with albumen printing, but I would bet that 99.99% is sufficient purity. As a matter of fact such a high purity of silver nitrate would not have been used at the turn of century when albumen was practiced. Even 99.9% would exceed standards used back then.

I was just doing some online searches for silver nitrate crystals and 1% gold chloride solution and I found that the prices can vary widely. $30-54 for 100 mls for the Au and .60 -.99 per gram for the silver.
With the silver nitrate, the purity affects the price a lot but doesn't seem to be a big difference in terms of purity.
My question to the group is, does a purity difference of 99.99% vs 99.995% make enough of a difference for albumen printing? My guess is that it doesn't but I wanted to check with the experts first! This purity difference makes a $30 difference in the price of 100 grams of AgNO3.
Also, has anyone had any experience with saltlakemetals.com?
