Dave, let me suggest that you run tests of this added "tooth" against a
test of plain size alone, to be sure it's having an effect. Some years ago
I tried starch, dextrin, diatomacious earth (or anyway two grades of
something made by Johns-Manville called Diatomite Functional Filler), and
a nice old rotted plaster of Paris (+ some others I forget), in an attempt
to add "tooth" to gelatin for something or other I was trying with gum.
They had little or no effect, although I imagine variables of the gelatin
& paper might also work differently.
