I use stainless steel so that it wont leach anything into the water Even the vessel is borosilicate glass as some of us found that regular glass could leach its materials such as lead. For me it made a difference. As for the polarity I have made it idiot proof.. If one required pulsing and a non silver cathode then dc only pulses would be required. . Im guessing your using AC for your design ...... to keep thr electrodes clean. I just swap out my stainless steel plates for the spare pair so that the stuff accumalates on a clean cathode and not fall down into the water where it would contaminate the brew

I have tried the carbon rod, from the center of a carbon-zinc battery, but it got plated with silver so I reversed the connections, occasionally, to unplate them. After that, I just use similar silver electrodes, so I can reverse the current, periodically, to cut the rate of silver loss from either, in half. I think, with a stainless steel electrode, you have to be careful of polarity and use strictly DC to drive the process, or you risk getting iron, nickel, chromium, manganese etc. in the solution. With two silver electrodes, this cannot happen, regardless of current direction. -- Regards, John Popelish -- The Silver List is a moderated forum for discussing Colloidal Silver.
