Sandy,
Sam showed me this trick of using dry dichromate a long time ago after
laughing at my first gum print. He must have taken pity on me. His prints are
wonderful.
Sam also showed me that if you add just a bit of dry powdered Viagra to the
mix the gum layer hardens faster.
Stewart Melvin's presentation was great. It was very thorough and I think
will help a lot of gummists out there (at least the struggling variety) procuce
better prints. I may even risk the critical review of Sam's keen eye and try
it again myself, by gum!
This was my first APIS and it was great. Met wonderful people and saw some
wonderful work.

<< Just for the record, Sam Wang has been using dry ammonium dichromate
for years and years in gum printing, and he makes some of the best
gum prints I have ever seen, vintage or contemporary. I am pretty
sure that he described his technique here on the list at some time in
the past.
From my rough calculation of the gum solution below (guess this is
from Stuart's talk at APIS?) it appears to be 20% (or even less with
the pigment added), which is of course well below saturated solution.
As I recall from Sam's work, his dichromate solution might be even
weaker than that, and as far as I know he is not using a roller or
anything like that to coat.
So why are folks using saturated solutions of ammonium dichromate if
it is not necessary?
