A while back, there was a discussion of clearing gum
bichromate prints in which Judy suggested that a long soak
seems to be just as effective as clearing with potassium
metabisulfite. Being somewhat superstitious about these
matters, I always use the clearing bath even if they "look"
clear (i.e. no dichromate stain). Am I wasting my time (or at
least my chemicals)? Perhaps you chemists out there could
fill me in on how to tell whether my prints are clear.
