Re: Please validate website claim and my method of making Colloidal Silver

"On the matter of heating one's water however, I'd say the prognosis is quite different. ie, while I too believe there is a reduction process at work in doing so, I'd add that there appear to be more benefits in heating ones water *during processing, than not."

Does the heating need to be done during processing? I do it after processing because I don't have a hot plate. I just boil the solution after processing. Is that not alright?

"A. In order to calculate the projected run-times for 20ppm, you'll first need to find out the total wetted surface area of the coin in question. - which would include both sides. That said, once you've found your surface area, you can use the following calculator to estimate your run-time and target ppm."

A nice and useful calculator! Just what we DIYers need. Thank you!

"In addition to this, depending on the size of your reaction vessel, it may be advantageous for you to use two small cathodes(on each side of the coin) so as to maximize the reaction surface area during production. Otherwise, the initial ramp-up stages won't likely include the entire coin - thus slowing the overall process"

I could make the cathode into a "U" shape and position it such that it's kind of surrounding (but not touching) the silver coin, right?

"one of the most important tools in making your own CS is that of a good stirring system. To which I'd add, while I'm sure bubblers can and will agitate the water, it remains that it is only with mechanical(magnetic) stirrering that the ions can be propagated away from the anode and toward the cathode. Which will in turn, greatly help in reducing the amount of oxide formation during processing(collecting at the bottom)."

Have you ever produced a solution that did not form any dark particles that you had to filter? Me never. It may be because I've always left it running too long. I start it in the morning before I leave for work and stop it about 10 hours later when I return home from work. I wonder if the CS I'm making in this manner is still good?

"the most important aspect of CS production would be that of a current control in your circuit. As this will stop the phenomenon known as runaway current, and keep your particle size(formation) under control throughout processing."

I'm already using a current limiting diode in my setup. But seeing your diagram, it seems that I placed the diode on the wrong side - the anode. Your diagram has the diode on the cathode. Well, I just followed an instruction I read that said to 'insert the diode in series with the (+) lead of the generator (anode). The stripe on the diode must point toward the power supply side, not toward the silver electrode or the alligator clip leading to the electrode.' Is this instruction wrong? I hope not, and I hope it doesn't matter which electrode you place the diode on. ;)
