High voltage is not needed to generate good quality CS. Talking of extremes, you may find this protocol interesting: There are many recipes for making colloidal silver, here is a very simple inexpensive CS generating circuit with good repeatable results. The circuit operates at about 12 V DC but you could substitute 2 x 9 V batteries for similar results, perhaps reducing the time using hot d. water by 15 mins and cold d. water by 30 mins. Parts: 1 x 9 Volt DC 200 mAmp (amperage doesn't matter, this was the cheapest), AC power outlet adaptor.[ you could use a 12 Volt adaptor, generating time would shorter for same PPM] 2 x alligator clips 2 x 75mm long, 2mm diameter .999 fine silver wires. Distilled water. Method: 1. Cut the end off the AC adaptor lead and split the lead for a couple of inches. 2. Connect alligator clips to the lead. 3. Plug the adaptor into the wall. 4. Secure the alligator clips to your silver wire, switch the wall socket on. That's all... I have tested this system in the arrangement as detailed below, and it produces 10 PPM (+ or - 2) CS: in hot d. water ------ 1.5 hrs (I heat in the microwave until just boils, 2 mins) in cold d. water ------ 3.0 hrs Arrangement: 1 cup (200mls, 7 - 8 oz) distilled water, with electrodes in the following arrangement, 2 x 2mm silver wire (14swg), wetted depth 45mm (1 3/4"), 45mm apart. I used a sterilite 1 cup, soft clear lidded plastic container with the electrodes pushed through the lid and parallel. The container dimensions are, 85mm (3 1/4") diameter by 65mm (2 1/2") deep. Colloidal Silver produced in this manner is clear (cold water) or has a slight yellow tinge (hot water) and needs no filtering. There is little metallic build up (trees etc.) on the cathode (negative electrode, - ) and little black build up on anode (positive electrode, + ). The plastic container will develop a yellowish tinge after a few batches, which will not wipe off. This is not a problem, and may in fact serve to isolate the colloid from static build up. I give the container a *swirl* every half hour or so. I wipe the cathode (grey) after I am finished and leave the anode (black). Rinse the container with distilled water and store with the lid on. Can't think of anything else... Hope this is of help. > Any comments or suggestions are very much appreciated. > > Thanks & take care, Vikki.
