From your description it sounds like your current was 1.5 mA initially.
Since your maximum voltage is 30 volts, I would expect the current to be
no more than a few microamps at the start, and approach or hit the 1.5
mA near the end of brewing. If it is running 1.5 mA initially, then the
water is not pure, regardless of what the meter says. What did you wash
the bottle out with? Any soap remaining at all can ruin the whole process.

Hi Guys,
I am very new to the list and I am sorry if am asking something that
may have been answered many times before (I couldn't find a FAQ .. or
a sticky post...).
It was from reading the excellent posts from this silver-list that I
have decided to make my own CS..
I used to buy my CS, however I decided to make my own CS primarily due
to the fact that the amount being used warranted that I make my own.
I got my friendly jeweler to rollout a Canadian maple leaf coin 99.99%
purity into a wire (bought from a respected coin dealer and also
tested with a silver testing kit, which gave me a rough idea that it
wasn't a fake coin)
Then made a very simple circuit arrangement using a 30V dc power
supply, into an lm338 and also tried with a lm317 regulator used in a
current controlling mode, set to 1.5ma (since i couldn't get it to go
any lower).
I am stirring the water with a motor which is spinning a plastic knife
around, in a 300g glass coffee jar, to delay agglomeration.
When used with distilled water (steam distilled by my friend with his
own distiller - he needs it for his silvergen sg6) - I have a water
meter that which measured 0 micro siemens for the water), I created
bits of silver that I could see visually... like very microscopic
glitter, which I know is incorrect and there were sparklies on top and
sludge gathering at the bottom...
I had an initial arrangement of 1 anode and 1 cathodes 15cm each
1.25mm wide exactly, and then placed them 2cm electrode to electrode,
which was really bad!...
I then made an array of 3 anodes and 3 cathodes 15cm each 1.25mm wide
exactly, perfectly parallel to each other, and then placed them 3.5cm
electrode to electrode...which helped significantly... but still not
perfect..
water is room temperature and definitely no additives like salt,
Bicarb or even CS!...
Voltage does indeed drop slowly over two hours, and current maintained
at 1.5ma and then hovers at around 5-6 volts which seems to be the
saturation point, when it first gets to around 6 volts i found its
around 9 micro seimens. but visible particles of silver.....
I thought at 1.5ma for even 1 anode setup that I would be ok, and not
overdrive it... but clearly something isn't right....
So I may have not done something right, or not understood the process,
or something could be faulty .. or a combination therein....
Would you kind people help shed some light on what's going on here.....
Many Thanks,
Asif.
