Marshall, You are correct about there being a limit to how close you can move the rods. I took that into account in my original post where I recommended the minimum distance to be 1.5 inches. The statement regarding constant current isn't correct in a practical sense. If you have infinite voltage available it is correct (and then the high voltage will cause other problems). I run my setup at 30 or 38 volts depending on the size of the batch I am making. I have two digital multimeters (DMM), one measuring voltage acrocc the rods and one measuring current. I also have adjustable current limiting but it is only useful if I have to be away from the brewing for an extended period of time. Even with using some high ppm colloidal silver solution as a starter, it takes a long time to get to current limiting at 10 ma. I haven't bothered to plot current vs time yet because I haven't yet settled on a standard process but one day I will. Once I have that settled, I can add alternating current and shutoff at a set ppm but until then AC will interfere with my DMM monitors.
Dee, IMO, you can move the electrodes closer, with a 1.5 inch being the minimum, for a significant part of your brewing without sacrificing quality because the very low currents that happen during the early period of the brewing.I do this myself when I am making 1/2 gallon or more at a time. I can't be more specific because I don't know what voltage you use, the size of your batch or if you use a colloidal silver starter. But you can always reduce time significantly by adding more CS as a starter. - Steve -----Original Message----- From: Marshall Dudley [mailto:mdud...@king-cart.com] Sent: Thursday, August 14, 2008 7:50 AM To: silver-list@eskimo.com Subject: Re: CS>Silver rods Dee wrote: > Hi Steve, what difference does the distance the rods are apart make? > How does this affect the time it takes to make the CS? There are at least two effects. First if the rods are too close together, then the ions simply move from one rod to the other, so some distance is required for them to get lost in the water between the rods. Second, if you are using constant voltage, doubling the distance between the rods will approximately half the current, and double the time to get to a certain concentration. If you are using constant current, and have sufficient voltage available, there is no effect on the current. Marshall -- The Silver List is a moderated forum for discussing Colloidal Silver.
