How did you make your electrolyte?
Did you use one of the posted formulas?
What was the temperature of the water while processing?
Why did you use a silver negative electrode instead of copper?
The black stuff on your silver electrode is gold powder.
I used the formula 50 mg sodium chloride, 75 mg sodium citrate, and one drop of corn syrup.
I use a lab adapter with the providing a current of 30 volts with 500 ma.
Although when connected to the power supply the current/voltage drops down to see picture ( 10 volts to 170 ma ).
Maybe the ab adapter is not strong enough?
I keep the water at boiling temperature.
I use silver rod thinking i could use it later for making colloidal silver water when ready.
Is this a problem?
Note;
Last night i tried another batch which failed again.
This time i spiraled the gold wire and let it sit just under the water level.
I noticed that the current provided by the lab adapter was stronger this time it dropped to 20 volts to 350 ma.
The first 12 minutes the water looked like it was turning nice and red but after it turned dark red brown and within 20 minutes the water turned into a beautiful violet color... I stopped the process.
I am guessing that although the lab adapter provides 30 volts to 500 ma it is not strong enough to do its job because the ampere and volts will drop down when connected? First i thought this is normal but i am guessing this is not good for making colloidal gold?
What do you think?
