photo-flo is used in Japanese Suminagashi marbling to make the inks
disperse.In suminagashi, water is the base onto which you float the colors.
in western marbling metholcellulose is the base when using regular
marbling inks. ox gall does 2 things. first it is a surfacant- a surface
active ingredient that enables the paint to resist the surfade tension of
the bath and thus to float. second the fatty ox gall surrounds each color
so it can't blend with another color resulting in a third color.
since these are 2 different types of marbling entirely, i doubt you
could substitute photo flo for ox gall.
i suggest you get a hold of " Marbling..a complete guide, etc" by
Diane Vogel Maurer and Paul Maurer, ibsn number 0-517-02019 to learn more
about the different types of marbling. There are other books, but this is
one of my favorites.
