I think the reason I had such a low ppm in that first batch (approx 6ppm) was that I had too large a resistor and not enough time for that setup. The max current was .444 milliamps and average current was about half that. Another problem was that, with no stirring and the current at .4 milliamps, I got whiskering on the cathode which implied to me that it was done. (12 oz distilled water) The second batch with very low current (.042 to .064 ma) averaging about .046 ma and running for 25 hours gave a calculation of 13.2 ppm. This was also with no stirring. I redid the salt tests and perhaps I understated the appearance of that. I think that I didn't put enough salt in. The salt test is only an indication. (Close = Horseshoes, Hand grenades, and Salt Test) I did a third one last night, 12 oz water, electrodes about 7 inches wetted shaped into a "U". I had a 1K ohm resistor (to measure current) and a 10K ohm pot in series. I kept the pot at 0 ohms until just over 3/4 hour when the current reached 1ma. Then I increased the pot to keep the current the same. After about ½ hour the pot was maxed out and I left it at 10K ohms. The current crept up to 1.142 ma after a total time of 2.5 hours. Average current was about .825ma. Also I had bought a small night light and stuck it in a tin can with a hole in the top for thermal stirring. Let me tell you, this is the way to go for watching what is going on in the cell! Just keep the room lights off. Anyway, the calculated ppm is 23.4 and I did get grey and black electrodes and a black residue when they were wiped off on a paper towel. But no whiskers. Very strong metallic taste. Clear in room light. Conclusions are that stirring is a must! unless you go for the super low current setup. 10K ohm resistor in this setup should be OK, even a fixed resistor although it would take a bit longer to get up to the 1ma level. I really want to get that current regulating diode (1ma) that was talked about a while back. (All things considered, the Silver Puppy is looking very good right now...)
