I have been making Colloidal Silver CS for thirteen years. I started with salt in the mix but changed to using a little of the previous batch to speed things along as Steam Distilled water is a very poor conductor. I have read that "Silver Salts" are not CS and as such are potentially toxic. I started out with two fine silver wires and three 9 volt batteries. The three batteries were clipped together two one side exposing a positive and a negative terminal. This arrangement allowed the batteries to bridge the top rim of the glass and the electrodes to be separated. Not perfect but it worked. You can get good results with old cell phone chargers. Presently I use a unit from SOTA Instruments which makes excellent CS and also doubles as an electronic blood cleanser (as developed by Bob Beck). I aim for a light golden colour which I will dilute into my Brita water filter. CS is also used in my cleaning products which are home made and usually also contain H2O2.
