This would apply if you were certain of what *caused* the yellowing.
If it were just silver then that would be ok, but what if it is the
silver agglomerating with something else? To me if it is mostly
clear, and then yellow sometimes, it is not certain what has caused
that colour. dee

The following would support my view, or I support theirs, whichever,

Quote: "True silver colloids that have a high percentage of the
silver content in the form of nanometer sized
particles will absorb visible light causing the apparent colour to
appear dark-amber, {my 'tea' colour}, or brown.
It is very high concentration of particles, not large particle size
or contamination, that gives these products
such colour." End quote. This comes from an article from CSL.
Probably depends on which published material one wants to believe, I
believe this, and my own visual observations over all else, not to
mention my tested samples of course.
That 1 micron 'colloid' I spoke of earlier would be the upper limit,
however, our particles/particle clusters would fall WELL under that
limit. Unless 'lumps' of silver are found laying in the bottom of
my container...it's all good, and the above quote is relevant.
