As one who spent most of the day yesterday trying unsuccessfully to
produce dichromate stain, I say you really know how to hurt a gal, don't
you! Finally at the end of the day I remembered about that
Photographer's Formulary gum that stained with some pigments, and I
found one of those mixes and printed it and did get some dichromate
stain. But there's no doubt it was one of the stupider ways I've spent
a day in my life.
