If you look at almost anything, animal or vegetable, even mineral, with a
powerful enough microscope you'll probably find irregularities, or holes
of some sort -- even in concrete. But the paper I speak of doesn't show
texture under a 10 power loupe, so could hardly be said to have "tooth."
The gum solution sinks into the fibers of the *absorbent* paper -- it wets
them and hardens there. It doesn't hang on tooth.
