Mostly Silver Hydroxide, a product of Silver Ions meeting Hydroxyl
Anions...sometimes some Silver Oxide and a little bit of metallic silver
....and a product of whatever else was in the water that an Ion or Anion
can react with to make an insoluble byproduct.
Ag [+] Ions and OH [-] Anions are produced in a 1 to 1 ratio, so why ALL
of the silver doesn't make Silver Hydroxide and Silver Oxide is a bit of a
mystery...but it mostly doesn't.
After the solubility limits of the water is reached, particles form.
High concentration zones can be local within the water, especially at the
surface of the electrodes...the Nernst Diffusion Layer..which is why
overloading that surface area with too many ions isn't a wonderful idea and
why a limited current density is important to prevent that from happening.
[Which also makes the process pretty darned slow unless you have great big
electrodes to spread more current over...which can get expensive in a hurry
'cause silver ain't cheap and making an electrode with little silver that
presents a huge surface area...like a metallic foam... is even more
expensive than the silver. ]
The further past the solubility limits you go, [ somewhere around 30 uS]
the more particles form, the more densely packed together, the more likely
they are to collide and make big enough particles to sink.
Some particles become lodged in the surface tension of gas bubbles
[Hydrogen / Oxygen produced by the electrolysis process] to be transferred
to the surface tension of the water when they pop.
If those bubbles are very *heavily* loaded and aren't very big, they will
sink and make a fluffy sort of sediment which will later release small
particles as the gas in the bubbles is absorbed by the water.
You will see a white "mist" identical to that which can be observed
streaming off one of the electrodes of a DC CS generator.
Warm water will hold less dissolved gas than cool water.
Warm water will hold more dissolved Ions than cool water.
Once a particle is made, it doesn't tend to dissolve...no matter *where* or
*when* it was made.
But, depending on what is holding bigguns together as a crystal nucleus,
Hydrogen Peroxide in very small amounts will scavenge something out of that
nucleus and break them apart into the crystals little fractal arms...making
littleuns outta bigguns and removing color.
Apparently, that something is the same as the black stuff on the
electrodes that H2O2 will dissolve instantly...Silver Oxide...variously
yellow, brown, to black in color, ..or no color apparent at all, depending
on concentration of the particles in the water and the density of it within
a given crystal lattice...along WITH, whatever particle size may be
presenting a color due to size...variously blue, green or red as well as
yellow in it's various shades.
But used too soon, H2O2 will actually Oxidize Silver Ions into a form of
Silver Oxide that Peroxide won't dissolve.....there are 5 possible Silver
Oxide forms [maybe more ]
..like Tetrasilver Tetroxide? [or maybe...Cowflopsilver Internetrite
Bullhockium ]
What the hey...if it works, use it.

No you don't. Just pour off the CS and leave the sediment behind. dee
