I know, obviously, that the intrinsic qualities of the paper arenbound to
be in part responsible for the result (maybe the sizing), but did the salt
do anything? Also, how would this mess up the archival qualities of the
print (if at all)? Is the result just due to the reaction being speeded up
in some way?
Anyway, serendipity rules - Alexander Flemming (and others) knew how to
exploit good fortune; so I will be doing some studies of this if no-one
else knows of such a "procedure" being documented. If the result is only
due to the paper I apologise for wasting everyone's time, but I got so
excited to see such beautiful blues (I've been searching for them for ages)
I am dying to know if anyone else has any information!
