When your silverware tarnishes, that's Silver Sulfide.
I doubt there are any free ions on your shelf or in a spoon.
But if you put that spoon in an Aluminum pan full of salt water or any
conductive solution, Silver ions do form via battery effect and destroys
the Sulfide compound.

"Ted from Bangkok, Thailand replies: "Agyria is a common problem with
using a straight batch of colloidal silver, often the skin is not really
blue, it is closer to gray color. The problem occurs when a free silver
ions react with the sulfur in your body to from AgS, or silver sulfide.
Most colloidal silver produced are actually either a nonreactive Ag or a
reactive Ag with a charge, then it reacts with the body's available
sulfur to cause a "blue skin", more more accurately is "gray skin".
This problem can be prevented, which I solved over a decade ago, which
required that a couple of drops of hydrogen peroxide is added to a liter
of colloidal silver. The peroxide, reacts with the FREE silver ions to
form Silver Oxide. When I first add this, I get a cloudly solution, and
after three days, this cloudy solution becomes a clear white transparent
water. However, an unreacted Ag or Silver in a solution will show itself
is a faint yellow transparent solution. So this ia an easy way to tell.
If you add a drop of H2O2 into this it becomes cloudy. However, if the
solution is Silver oxide, it won't become cloudy as there is no longer
any "free" silver ions. When they are no longer free, it won't react
with the body's sulfur to form silver oxide. Hence, if a hydrogen
peroxide, at least, is added to the colloidal silver you buy, the silver
is no longer free, and the condition of blue skin or gray skin or agyria
is prevented.
However, there is ANOTHER way, that DOES NOT REQUIRE you to wait for
three days to fully digest the free Silver. When I make a batch of
colloidal silver, using the silver wire or silver rods as an electrode
using any D.C. adapter, the BEGINNING solution is distilled water with a
0.5% H2O2 concentration, which is 1/2 percent H2O2 concentration, or
approximate amount such as one tablespoon (plastic spoons!) of 3% H2O2
in a 1 or 1.5 liter of colloidal silver is generally sufficient, to
prevent any free metal silver form occuring.
It should be noted that a silver oxide may have a better antibacterial
properties and less staining problems then the use of pure silver. So in
practice, the use of COLLOIDAL SILVER OXIDE, is the one I actually use
and relatively problem free. For example, if a free silver has too much
charges, I have noted that constipation occurs if taken too much of
colloidal silver with FREE SILVER, but this doesn't happen (within
reason such as NOT DRINKING liters of it!) if a COLLOIDAL silver oxide
is prepared."
