I have read suggestions that the gelatin on the *final* transfer sheet, after
development and cold wash, could be hardened in alum (standard silver/gelatin
hardener) for greater protection, or if another layer was to be transfered, say
for tricolor printing. On the tissue it would immediately kill it.

I checked tube $2.89 is for 38 ml size of gouche. I have some bottles
of *concentrated* water color meant for airbrushes. Very inexpensive.
Can't use for gum, stains too much but may work with gel. also $2.89
