It sounds like you're doing great, Jim! How are you holding the silver in the water? I hope that only the silver is in contact with the water, otherwise you're making colloidal <other stuff>! Besides that, I think your setup and procedure sounds fine. > There were strands visible coming from the positive electrode after > about 15 minutes in each run, and at the end there was some slight > amount of black residue in the bottom of the jar. Do you wipe off the electrodes when you take them out? It's easy to shake stuff off the electrodes when you remove them to stir and make your measurements, so that can account for a little fallout in the bottom. Also, there sometimes is some part of what's coming off the positive electrode that tends to sink and plate out on the bottom of the glass. > The only pressing question is if this dark color change is normal, > and what is causing it? Did I let it run too long? You're probably just fine. As a wild-assed guess, I'd bet your actual ppm reading will end up maybe 15-20. I think you are reaping the benefits of large surface area electrodes. Your setup can absorb a fairly large current flow without making the really big particles. Let me know if you see any additional fallout after the first day. Keep a sample to see if it's still clear with the bottom of the bottle clean after a couple of weeks in a quiet place. Then you'll know if you've got a reasonably stable conconction with adequately small particle size. We see the initial color change during the first half day or so as the particles get settled in their new home. <grin> I suspect a bit of clumping and moving around for a uniform distribution is going on. There might be some chemical changes happening at the surface of the silver particles, too, but in the long run things become quite stable and the stuff seems to work just fine. Good going! The more you make, the more you'll get the hang of it. Let us know how it works for you! Be well, Mike D.
