I've always suspected that the color was due to
oxidation but have absolutely no evidence that this is the
case. I have a set of silverware that I've noticed
exhibits the same sort of color change as it oxidizes. If
this was the case I would expect to see a greater color
change (more rapid oxidation) with the larger particle
sizes (greater surface area per particle). One other
anecdotal input...if I place a recently cleaned piece in my
mouth I don't get the same taste as I get from a heavily
tarnished piece. To me the tarnished piece tastes close to
the metallic taste I get from the darker colored CS.
For those of you who may take exception to this
just tell me one thing... what is the process that
prevents the silver from oxidizing in the presence of the
oxygen in the water?

George Martin
