ANONS TALKING ABOUT COLLOIDAL SILVER
from previous bread(s)
Your electrically generated c.s. will be cleaner and better if you use a lab stirrer. A cheap one will do, being low viscosity.
EBAY sells the stirrers for as low as 20 bucks with magnet bar..

Also as a note: An old laptop power supply is between 15 and 22 volts, will be just about perfect for making CS without using batteries.
Just find a matching barrel plug (or cut the end off and strip back wires). You want to use a 250 ohm resistor and an LED in series to prevent over current and burning out the supply in event of rods touching.
I used a "three terminal" screw block, with a paperclip on one terminal and silver rods on the other two, spacing stays parallel better that way and the paperclip stays OUTSIDE of the vessel (glass) so the rods do not "fall deeper" into the glass. And the stirring action rotates the liquid thru the rods better. Makes a superior product in only 15 minutes.
There are about 30 of those mixers left at that price on ebay.
For the silver rods:

Get the 12ga 1ft .9999 pure wire.
Cut in half for 6inch rods.
THE WHOLE THING is less than $50 and will make GALLONS and GALLONS of "free" silver for years. (rods will eventually deteriorate, but you can swap the polarity when one starts looking bad, so the other one will wear evenly.) - hell, get TWO FT of wire and don't worry.
Done for years.
