Hi Kathryn. I dont know if this got posted to the list or not so I will repost.
Need more info. What size batch are we taking about? What was the current .2-,3 or ,275 mA? What are you using for Electrodes and what size. Whats the spacing on the electrodes. At .275 mA I would run the batch 24 hours per quart with electrode spacing of 1.5 inch's using a total of 12 inch's of 12 gauge wire (6 inch's per electrode).. If you take a peanut can , drill a one inch hole in the top center and a one inch hole in the side, put the light bulb in the hole in the side and the cs on top, this will work good on a short glass jar. The thermal stirring wont go above 5 inch's or so. The batches I make = 50 ppm or so on the Faraday calculations but some of the silver is left on the electrodes or on the glass container. The cs stays clear most of the time. Faraday calculations work but their are many of other factors involved to produce a good CS. Stirring is very important as is current control per sq inch of electrodes. Ode from silver puppy sells a magnetic stirrer of which has solved many of my problems, I have used very low current before with somewhat good results. I prefer to use 1 mA of current per 12 inch's of 12 or 14 gauge wire or .5mA per square inch of total wet electrodes. Hope this helps. Sam L. On 12/7/06, bs clayton <[email protected]> wrote:
I am looking for some input on this new batch I did. I changed 2 of the parameters, adding a light bulb under the jar as a thermal stirrer, and I lowered the current to .2-.3 mA. So I have a 27V battery (3 nines) hooked up in series with a potentiometer and a multimeter, with the jar now sitting atop a clear xmas light bulb, I ran it for 9 hours, wiping the electrodes off once and switching the polarity once, just for kicks. It had a faint Tyndall effect when I turned it off. According to my Faraday calculations, it should be 8.33 ppm. BUT it has no Tyndall effectnow, after sitting overnight, which every other batch I have made has had, but those batches were at 4 mA, not .275 mA. So I am missing my visual cue. Are the calculations real? Is this stuff strong enough to use? By the way, the water was really good, no conductivity at all that I could measure with my ohm meter. And this is my first try with very low current. Kathryn ____________________________________________________________________________________ Need a quick answer?
