I remember in the old books talk of "spontaneous hardening" and they would
blame it on unsuitable pigments, and one guy even wrote this whole theory on
how the minute you put dichromate into the gum/pigment mix, it hardens, and
then it get less hard...pretty funny and I only read this idea once so
apparently his explanation didn't hold water.
