Alberto,
OK, so I've melted up two teaspoons of dry pigment (raw umber, burnt umber, and ivory black) with a teaspoon of violin bow rosin over a gas burner and have reduced the resultant mass to a pile of powder by grinding it on a piece of sandpaper. It looks to me a mixture of very fine to rather not-so-fine particles.
Regarding the gelatin: Your notes say "The gelatine must not melt, once swelled in water, below 30°C." The gelatin is simply swelled in warm water and coated on the paper? I've never worked with un-hardened gelatin, so I have no real experience with this, but I'm skeptical as to how this gelatin coating will withstand a rather lengthy wash. Am I missing something, or is it really this easy?
Thanks!
Keith
