No, Thomas, that's the true cost of silver for a particular hand-coated alternative process. It doesn't correlate at all with the silver in industrially manufactured silver papers. The most reliable information I've found pins it at 0.9 to 1.2 grams of silver per square meter of black and white paper emulsion (film has more, as does color paper, surprisingly).You guys are confusing the coating process. Raw silver grains are not deposited on the paper but are dissolved in a solution such as silver nitrate and then that solution is then coated onto the paper. Posted a while back on the forum was a 1950's film of how Kodak manufactured film. It showed the manufacturing process from beginning to end and stated that Kodak used 40 tons of pure silver a month in the manufacturing process. To do that you need a lab, capable and highly trained workers, equipment...shoot you need a factory building. In my own personal example none of the labor or equipment cost are factored in. As far as the actual amount of raw silver deposited on each sheet of paper then simply answer the following HS chemistry problem:Thomas, even in your own idiosyncratic example, it seems the cost of silver is insignificant compared to the cost of the paper. Most of your silver is excess, as opposed to the 50% utilization rate of manufactured silver papers.
If the price of silver is $32 per ounce what is the cost of the silver contained in 2mL of a 10% solution of Silver Nitrate (AgNO3)?
Hint: Use dimensional analysis to find the answer.
