The following would support my view, or I support theirs, whichever, regarding
colour...
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.
