Lowell -- to reply to your question about glaciata vs. ghost plicata....
With "ghost plicatas", the anthocyanin (water-soluble) pattern is
formed, but can be expressed in but a limited degree, due to
suppression.
With glaciatas (formerly referred to as ice-whites, lemon ices, etc.),
NO anthocyanin is formed, not even the merest hint. What you have left
is the ground....the canvas with no plicata (or luminata) paint applied.
Which, incidentally, is what makes glaciatas so fascinating. Since they
are incapable of producing any of the cool-colored water soluble
pigments, this allows the warm-colored oil-soluble pigments to appear in
absolute clarity, with no greying effect from the anthocyanins. In a
glaciata there will be not so much as a single dot or line at the haft,
no greyed suffusions.
