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 30C."  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
