Carlos, In practice, it takes a finite amount of time, every time the polarity is switched, for the flow of ions to stop and reverse direction. During that time, ion production is less. So in practice, a polarity switched setup will produce less silver in solution than an unswitched version, keeping all other parameters the same.
Some people, myself included, just switch electrodes every batch to keep electrode wear the same, and don't bother with the extra complication of polarity switching. Going another step, if you reduce the constant current to about 0.2 milliamp (0.0002 amp), so that your production takes 24 hours, you can eliminate stirring as well. The normal Brownian movement of the water will be all the "stirring" that is needed. If you need higher production, your wall adapter can run up to hundreds of 1 quart CS generators at the same time, each consuming only 0.2 milliamp. Just add a 0.2 ma constant current diode in series with each quart brewer & connect them all to your wall adapter. An ppripriate diode is 1N5283 (0.22 ma), available from Mouser. --Steve Y. ----- Original Message ----- From: "Carlos PĂ©rez" <explorer...@hotmail.com> To: <silver-list@eskimo.com> Sent: Thursday, November 23, 2006 1:57 PM Subject: CS>Polarity Switching ?...-Some thoughts about it. > Friends, > > From what I understand, the object of polarity switching in the process of > brewing AIS is to eliminate the normal silver oxide accumulation in the > cathode and the harder coat of silver oxide in the cathode, which maintains > both electrodes clean. > > A determinate ammount of silver oxide will be produced in batch "A" without > polarity switching, which at the end of the process will have produced a > noticeable moderate dark grey "beard" on the cathode. > > If we have an identical batch "B" (identical water quality and ammount, > temperature, process time, current flow, container, electrodes, etc.) and > have polarity switching during the process, I assume aproximately the same > ammount of silver oxide will be produced, but instead of accumulating it is, > in every switching of the polarity, solving into the water, aside from the > ions and colloidal particles being produced. > > If, after batch "A" is finished, the current is stopped and the electrodes > left in the produced EIS, after a few seconds the cathode "beard" starts > turning into a "cascade" mostly dissolving in the produced batch, and a > smaller part sedimenting at the bottom of the glass jar. > > If this is the case, the only basic difference between "A" and "B" would be > cleaner electrodes in "B".
