Ions, by definition 'one atom missing or with an excess of electrons'
[in the case of silver, missing one electron ] and have a very strong like
charge on the electron shell / atomic level...they CANNOT cluster any more
than you can force like poles of a magnet together.
In order for a "silver" particle to form, the ion must pick up an electron,
but there are no electrons in a liquid to pick up.
The only places a silver ion can find an electron to become a **metallic
silver** particle is at the air/water interface of the electrodes and the
surface of the container acting as a capacitor whereas electromagnetic
radiation is depositing electrons onto the surface of the glass.
Most particles that form are silver hydroxide [AgOH], made when the silver
ion Ag[+] finds it's counterpart made in a one to one ratio with the
ion...the Hydroxyl anion OH[-] [that white mist ]
Another that can form is a silver oxide particle where silver ions react
with the byproduct of electrolysis, oxygen, forming AgO. [that golden
mist..if the current is so high as to force it to form in the water vs on
the electrode]
Particles have no charge, are only held apart by a weak van der waals force
which can easily be overcome and particles be forced together by kinetic
collisions etc....and agglomerate into clusters.
Clusters are often crystalline, forming around a nucleus such as a silver
oxide particle.
H2O2 will destroy an AgO molecule leaving such a crystal without a nucleus
and it's fractal arms will float away as smaller particles.

But if H2O2 is used before all the byproducts have done whatever they are
going to do with the silver ions, H2O2 will oxidize some ions forming
[probably Ag02 ..one of 5 possible configurations of silver oxides,
excluding possibilities of silver peroxides ]
BTW.....A yellow color can be BOTH an oxide pigment AND a blue light
absorption due to particle size....at the same time.
...and if H2O2 is in the brew water while brewing, it can set up things to
donate electrons to the ions, if done to the extreme, making shiny silver
metal flakes.
Likely, if the balance is just right...a high proportion of metallic silver
colloids can be made that way.

I believe the 'colloids' as referred to are ions which have clustered
together in solution, with each ion surrounded by or encased in water
after the ion clusters - particles - are formed. ExampleÂ…A bunch of
balloons all touching each other, each balloon is water and inside that
balloon is a pea, in this case the pea would be a silver ion.
Ions are in rapid and constant movement in solution {Brownian Motion}
hence it takes time for the solution to stabilise while ions are colliding
with each other forming ion clusters - bunches of balloons.

Subject: Re: CS>CS & Hydrogen Peroxide = Cloudy?
Just curious, isn't colloidal silver a colloid once it is made? Why does
it take 2 days settling? BTW, it was probably 4-5 hours after the Silver
Puppy shut down when I added the H2O2.
Often it will turn cloudy if you add it immediately after brewing. Most
people wait about 2 days after brewing before adding H2O2.
