And as I was saying in a conversation with Henk last week or so, no one
really knows for sure whether pigments that are fugitive in themselves
are equally fugitive once encased in hardened gum. I assume that the
answer is yes, so I don't use fugitive pigments. But until someone
actually does that fade testing, we're all just guessing; maybe you'll
do those tests, Chris...
