DEAR LIST,
I seem to recall in past postings that certain "food" items could be
used in alt photography.
For example I read that a saturated solution of MSG could be used to develop
PT/PD prints. I also recall that either Sprite or 7-Up had enough
phosphoric acid in it to be used as a clearing bath.
I would like to add a few. Most "Iron tonics" used for anemia
contain ferric ammonium citrate as their "iron". If I mix them with a
bit
of Potassium Ferricyanide solution I could make some cyanotypes, yes?
I returned from Paris with a nasty flu and have been taking
Buckley's cough syrup with its characteristic high gag factor ammonium smell
& taste. When I read the label it stated that it contained Ammonium
Carbonate. Soooooooooo, if Eric Neilsen will tall me the right amount of
citric acid to add, I guess I could make an Ammonium Citrate PT/PD
developer.
I must confess I find it scary to consume anything that can either
develop or clear PT/PD prints but I guess this is "better living through
chemistry" as our old pals at DuPont used to say.
HOLIDAY CHEERS!
