Hi Mike, I made that particular batch on June 21, 2001 when I was designing the SG7 Pro and was using different current ranges to see what the relationship to current density versus production speed versus "end product quality" was. That batch was made using 30 milliamps and four electrodes 1.5 inches by 6 inches spaced .5 inches apart and wetted to about 5.25 inches. The electrodes were paired so that numbers 1 and 3 were connected together and numbers 2 and 4 were connected together. When current was applied odd ones were positive and the even ones were negative. I reversed the polarity ever 45 seconds as I recall. Stirring was done using a submergible fountain pump. Stirring was vigorous.
My recollection is that I used water distilled with our Barnstead still. Conductivity is usually around 1.0 uS. I sometimes buy store brands to see what their readings are and to get a reference point. They usually read about 1.5 to 2.0 uS. This is the same setup I use today for the SG7 Pro. Starting voltage is around 75 volts. I also made some at 50 milliamps using 8 electrodes around the same time period. It's 30 uS and is still clear and colorless. I cannot remember the last time any CS turned yellow with our stirring models. I can make it yellow with the SG5 but it doesn't stir. I use a current limiter and when the voltage drop across the electrodes equals the setting on the PPM dial a comparator senses that and shuts the generator off. I stop the pump when I think about it. Sometimes most of a day goes by before I notice the pump is still running. Once voltage is removed from the electrodes stirring doesn't affect the CS. I make gallon+ batches almost every day and don't decant, I have a spigot in the container located near the bottom and just drain the CS into gallon DW bottles. I've never seen any silver in the water or seen any floaters when pouring out of the jugs. I assume they have fallen apart from the force of draining through the spigot and are in the water. Using a laser pointer doesn't show any sparklers so they must have gone to the bottom as you say. Or ??? In any case they aren't visible. I have had some customers want the units calibrated to at least 30 PPM so I crank the upper PPM shutoff setting higher but always give them the caveat "if it turns yellow" don't turn the dial so high. But I don't get feedback telling me they have any problems with agglomeration so I guess it works for them just as it did for me. I normally calibrate them to 20+ PPM. I hope this helps.
