I was listening to 'Today' on Radio 4 one morning over my porage. It was
the centenary of Coca Cola leaving cocaine out of Coke. They commented on
the present recipe to the effect that it contained phosphoric acid which is
also an effective spermicide. Phosphoric acid is an effective developer
for Pt/Pd prints using the classic Willis method. There is enough of it in
Coke to develop a print but, I am to;d that it is best to use Diet Coke as
there is so much sugar in standard Coke that your print will become
birthday cake for bugs. I tried it on a demo once when I had left my
potassium oxalate at home. I call the resulting print a 'Dietcokeotype'.
