For the last several months I have been working on variations to
the gum-bichromate process. I've discovered that soy beans,
milk, boiled pork, and gefilte fish work in place of gum arabic,
and that most any soil or rock forms a functional pigment.

The big problem turns out to be in spreading the goop evenly,
and in the right thickness onto the page.

How do you do it?

I have heard about a number of techniques, all of which suffer from
low reliability. It is almost as though goop-ing is the black art
in this form of photography.
