Very interesting.
What you are showing is that you can make a very strong brew
in water (with added salt) in a short time.
I would rather record the actual current every few minutes
and graph and calculate from that as you can get a better
idea as to what is actually happening. If you have
Microsoft Excel you can use the Faraday calculator to do the
math.
My purpose was somewhat different. It was to show that you
could make a less risky and still useful product in tap
water, if necessary.
I will have to do some more detailed experiments.
Note that if you have a CS maker with current control you
will never get more silver than the current limit will allow
which is approximately:
17ppm at 1ma in 1 cup of water for 1 hour or
.28ppm at 1ma in 1 cup of water for 1 minute.
So with a 1ma current limit, go ahead and brew for an hour
to get 17ppm (in one cup).
Otherwise, using a 9 volt battery with silver electrodes for
1 minute in tap water in about a 16 ounce glass (with manual
stirring) would probably give you something that you could
use in a pinch (without salt). This might be useful for
sterilizing water or treating diarrhea.

I've tried to re-create the 'old method' of making Colloidal Silver with
a glass of tap water, a pinch of salt, and 3 x 9v batteries with no
current control. This was the method used by Stan Jones, (and perhaps by
the new blue man, Paul Karosan)
I started with a brand new 12 gauge pure silver anode (and cathode).
7 cms was submersed. I calculated that this weighed 2.3 grams or 2300
milligrams. (Based on 'ccsilver' website information 34'' = 1oz. or
86cm = 28g). The electrodes were spaced about an inch apart.
After 60 MINUTES of brewing time I observed the anode. It was visibly
VERY reduced. I estimated it had lost half its volume.
So in one hour, 1150 milligrams of silver had been dissolved in just 250
mls of water.
This equates to 4600 ppm.
As the conductivity of the water was 'consistently high' throughout the
brew time I estimated that after 10 minutes the milligrams dissolved
would have been about one sixth of the final amount , or about 191 mgs
in 250 mls.
This equates to 764 ppm (Produced in just 10 minutes remember.)
So any assumption that this old method makes about 1 ppm per minute is
completely wrong by a factor of about 70.
And I doubt that omitting the pinch of salt would have made much
difference because the conductivity of the tap water was pretty high
anyway. (So making CS with anything other than pure water is a bad idea.)
You'll also note that the calculations above are exclusively limited to
the milligrams of pure silver that was actually dissolved. I have no
idea what that would equate to in ppms of silver chloride.
Compare this to one of todays current controlled Silverpuppys or
Silvergens for example. After 3 or 4 hours brewing time in pure water
they produce about 15 ppm. (Or about 3.7 milligrams in a 250 ml glass of
water) And no silver chloride.
Meter readings don't mean much in a test like this but I recorded them
anyway with a HM Digital COM100.
Tap water: 324ppm / 660uS
Pinch of salt added: 990ppm / 1950uS
After 30 minutes: 1330ppm / 2650uS
After 60mins: 1820ppm / 3450uS.
Actually, I was surprised to see the conductivity increase. I expected
it to remain virtually stable with dissolved silver combining with
impurities to form non conductive particles.
My power source was a DC wall transformer that output about 29v.
