Re: Palladium on vellum
Hi Keith, actually that was "my" question to people on the list :) I remember reading somewhere (could be "tracing paper" entry in wikipedia) that when you treat paper in sulfuric acid, the fibers somehow change, making the paper more translucent. I absolutely don't know if that really works or if that is doable at home. (If yes, I don't know what dilution, for how long etc.) Was just asking if that's possible. You bet that I have this on my "to try" list... but not too soon. I could use a much more translucent Masa for a la Burkholder / Matusz gold leaf technique... Masa is more than adequate and robust enough for most iron processes.
