Interestingly enough, if it appeared that there was a real difference of
informed opinion that needed scientific investigation with 'heavy machinery',that
could be arranged. We could even have a paper about at APIS. 2006. But, at the
moment, as is suggsted here, the observed realiity with pigmented and
dichromated gums and gelatines is that they harden from the surface of the coating
down to the surface of he paper.
If the effect you are dscribing is occuring, my reaction is that you are not
achieving the as good a combination of gum, pigment and dichromate as you
could.
You are right in that there is far too much specualtion here. I am afraid
that is too often the kind of speculation that cannot, as you imply, be taken
seriously. The principles involved are simple as are the techniques needed to
apply them most effectively. .
My own techniques are set out on my web site.
