The best way to make colloidal silver is to know how to make it in detail, and then put together your own set of manufacturing equipment. (This information will be coming very soon). Other people would be happier using a ready-made machine. Those people who would like to buy a machine and are wondering which one to choose, may benefit from this article.
I have spent many hundreds of pounds buying and testing factory-built machines, and for those who want to use a “turnkey” solution, then I have put these notes together. Be advised other machines are available; I have only tested (and bought) those mentioned here.
SilverTron: The best, most accurate and repeatable process is made possible by the SilverTron I machine, sold by Bill Peters (Kephra). I was fortunate enough to get one of the first production machines. As it calculates the amount of silver released by the anode, regardless of changing amperage, it produces an accurately-calculated ppm of CS, and can be programmed for varying results. These are still for sale; the SilverTron store is http://www.silver-tron.com and the support forum is http://silver-tron.com/support/. Bill also produces a less computerised version called the SilverTron Junior, which is a more basic but fully-adequate machine. Those owning them have the assurance that they have been made not only by a skilled engineer, but a chemist who has full understanding of the process required. It is mains-powered, but takes a 9 volt input, so could be adapted for batteries.
SilverGen: I have an SG6 and SG7Pro. Both of these machines are mains-powered and are designed for making IS (Silver Oxide) straight out of the box. They can be adapted to make the other forms of CS quite easily, or one can make IS and then boil it in a microwave or add a drop of Karo/Golden Syrup to reduce it to true CS as desired. The SG6 does not reverse polarity while manufacturing, whereas the SG7Pro does reverse polarity to reduce the oxide build-up on the electrodes. Whether you regard this as an advantage or disadvantage depends on your personal opinion. Polarity reversal means that you need to use two silver electrodes instead of one and it is slightly more difficult to calculate the ppm of the final product. The SG6 is quite a lot cheaper, as the SG7Pro has a very large silver array in order to run at a much higher amperage (about 45 mA instead of 15mA) and is designed for bulk production. If I could not get a SilverTron, I would opt for the SilverGen 7 Pro if funds allowed. The SG6 is also excellent, however.
To modify these machines to make golden-yellow reduced CS: SG6 – just cut an electrode in half lengthways to make two thin strips of silver out of a single electrode, and buy a set of leads to connect the machine remotely to the jar in which you are making the CS, as the heat will otherwise cause steam to rise up into the electronics. SG7Pro – use a fine-bladed hacksaw to cut out the centre two electrodes, (one anode, one cathode). Then open the electronics box, find all the small trim-pots inside the case, and using a fine screwdriver, turn them clockwise to the stop. Be advised that this will invalidate the warranty.
GoodVitality ST4: The above machines are all made in the USA. Good Vitality is a UK company which is run by an electronics engineer who also has an interest in alternative health techniques. His units are well-made, and are battery-powered, which could be an important factor for anyone who doesn’t have access to mains power. The unit will make golden yellow CS straight out of the box, and the maker recommends the heat-reduced process. Excellent machines. He also offers a current-reversing unit which has a dual-purpose as a Becks Zapper.
I have not used the Silver Puppy or Sota units, but they should be fine.
The main issue with all commercial machines, is that few manufacturers have any detailed knowledge of the processes involved (Good Vitality is an exception, but even he mistakes heat reduction for higher ppm – this is not necessarily the case). The user of a commercial machine is advised to consult this site for the principles involved, and then use the machine with the knowledge of how the machine is carrying out these principles.
I have spent many hundreds of pounds testing commercial units, only to use my own “home-made” set-up now. That should tell most people that they may be better off making their own home-made production set-up, but each to their own.
Disclaimer: I have no financial interest in any commercial machine or manufacturer. I am just recommending what I have used.
