Hi Trem, Yes, thank you very much. Your parameters are very interesting and I would like to study them more carefully. Can your give the exact volume of dw and the brew times?
You probably won't see any floaters with the vigorous stirring - they are very fragile and would be blown away. Also, reversing polarity would likely prevent any buildup. With a starting voltage of 75 volts, you must be running fairly high current density. Also, this would require a discrete current source since no integrated current regulator I know of will handle more than about 36 volts between input and output. Is this true? The high voltage seems to indicate you are running at higher current density than most cs generators. The Nernst diffusion layer should be quite dense, and there should be a lot of combination of Ag+ and OH- ions at both electrodes. This produces the neutral silver oxide particles that agglomerate and cause yellowing, as well as a strong Tyndall. Some of the reactions are: Ag+ + OH- --> AgOH AgOH + AgOH --> 2AgO + H2O The Nernst diffusion layer must concentrate the ions to quite high density to allow this reaction. I have allowed a glass containing 1 inch of 20 ppm cs to evaporate down to 1/8 inch (took weeks!), and it remained clear with no hint of color. The final ppm must have been at least 20 * 8 = 160ppm. The salt test showed enormous flakes of silver chloride that were visible without a microscope. So it takes even higher concentration than this to convert significant numbers of ions to the various silver oxides. With the three nines process, the exponential current rise produces very density at the end of the brew which limits the ppm to 10 to 12 or so. Using lower current density allows higher ppm, perhaps up to 22ppm before significant yellowing starts. So the vigorous stirring in your system may disrupt the Nernst layer enough to reduce the conversion to oxides, and you get no yellowing. This is very significant!
