Ok, I have tried to put all the information together from the
responses yesterday of platinum costs but I still have some
questions. Clay says that he needs about 4.8ml of the metal salt for
a 20X24" print. Is that the equivalent of 4.8ml of the Platinum or
Potassium Solution #3 that I am using, which are both 20% solutions?

Here is what I figure that is needed to fully tone a 20X24" kallitye
print with platinum or palladium #3 solutions. I prepare one liter of
toning solution using 5ml of the #3 solution, which according to my
estimates amounts to only 1g of metal, since it is a 20% solution. To
tone the 20X24" print I use about 200ml (or 1/5 of 1g of metal salt)
of the working toner solution, so I calculate that the amount I am
actually using to tone a print this size is 0.2g of palladium or
platinum. Do these figures make sense, and if so, what is the
equivalent amount being used to make a real Pt/Pd print?
