<< W&N were fine enough for gum. He claimed that Wm Mortenson (I can never
remember how to spell his name) would buy dry pigment and ball mill it. This
is a process where the pigment is put in a can with some 1 inch size ball
bearings and the can rolled on a device similar to what rock hounds use to
polish rocks. This process can take weeks I was told. >>
I remember Todd Walker saying that he ground dry pigments with a mortar and
pestle. I seem to remember he would add the gum as he ground the pigments.
I tried this and found it to be messy and for me didn't work any better.
