I'm with Ron, don't know what machine you are using? I can't speak for those "polarity reversal" machines but if it's not one of those then you need to remove electrodes front the water at regular timed intervals to wipe them clean before re-submerging them. The low voltage will make the process take longer. Again, don't know what machine you refer to regarding the 32 VDC? My homemade machine runs on 24vdc and I get around 17-20ppm in 1 1/2 to 2 1/2 hours dependant on water room temperature. Is the machine current limited or controlled? If not then you will get current "runaway" which encourages all that gunk to develop. The more silver dispersing in the water, the more conductive the water becomes and strips silver off electrodes quicker, it's an exponential thing. That "gunk" is normal, but only if the electrodes are not removed and cleaned at regular timed intervals, or if the machine is not current controlled or limited, or if the machine hasn't the auto polarity reversal facility. My machine does not have polarity reversal so I remove electrodes from water each and every 30 minutes to wipe them over, if they need it or not, then swap the electrodes over manually to change the polarity on the electrodes before re-submerging them. As the process progresses however, the quicker that gunk will begin to form. The silver hydroxide and oxide, the "gunk", I'll leave to the experts to explain, all I do is keep that to an absolute minimum. The only reason for throwing the first batch away perhaps is due to any coating which may be on the electrodes from manufacture? 5 minutes brewing in mains water or rain water will get rid of that, then wipe electrodes clean and use only distilled water forever more. Measuring ppm? Any TDS or PWT or whatever meter will get you in the ball park, none are accurate for silver preparations but at least you will know when to shut the machine off at your desired ppm with every batch you make. Meters won't indicate the particle content, hence they miss some silver content on the reading. You will in all likelihood have more *total* silver content than any meter will indicate. N.

The voltage is adjustable from 3.7 – 11.7 VDC. I was surprised that it would not go up to the 32 VDC that I have read about. Do you think that something is wrong?2. If nothing is wrong, what would be the better voltage to set it at and why?3. I ran the machine for 2 hours and got 7 ppm. Is that normal?4. I continued to run it all night (about 14 hours) and got 15 ppm. Is that OK?5. The negative silver wire is solid black. Is that normal?6. The positive silver wire was covered with what looked like ¼ inch of brown jelly something? Is that normal?7. The bottom of the jar was covered completely with about ¼ inch of the same brown what ever? Is that normal?8. The CS itself is basically clear.9. I will filter the CS through a coffee filter. Is that right?10. I am supposed to throw away the first batch. Is that right? Floyd Floyd This email has been checked for viruses by Avast antivirus software. www.avast.com
