The silver acetate seems to go for about $2 USD per gram from
"legitimate" sources, less from ebay. They mix 1 g with 2.5ml of
ammonium hydroxide plus .2ml formic acid. Assuming you can get 2 ml
of ink from the mixture and that the cost of the ammonium hydroxide
and formic acid are negligible (???), the cost would be about $1
USD/ml. Since you are only drawing traces, it shouldn't be too
expensive, especially if you can reuse any ink wasted in head
cleaning. Anyone interested in a group buy of the chemicals?
