Dilute copper sulphate solution makes a good invisible ink. If you heat things written with it it catalyses the charring of the paper and the "writing" turns black.1. If you char the paper, the image will remain visible after that. I thought we were looking for something reversible.
I don't think you could easilly get the stuff dehydrated by heating it because it would char. You might manage with a dessicator.
"don't have an answer, but I am wondering how you intend to apply the ink without being able to see it "
You could load it into a printer.
DO boiled potatoes really go brown faster that mashed?In my experience it is the RAW potatoes that brown faster, when cut and exposed to air.
