I have a question that has been bothering me lately. In reading my references for pt/pd printing some people use 450 gr of PO in 1350 ml of water, some use 200 gr in 1000 ml of water, and I am wondering why so much?

I have not calculated the stoichiometry of developing Pt/pd but lets say it is one to one. For example it takes 1 gram of PO to reduce a 1 gram of pt/pd to its metallic state, why use so much then in the developer solutions? Has anybody tried using less? In a pt/pd print depending on the size typically there is from 1 to 4 or 5 grams of pt/pd so I am thinking.....heck if I make a 10% solution I should be good to go.....

I know some are thinking "why dont you try it dummy?"...I will but is always good to ask so that you dont waste valuable solution on something someone might have done before....
