Basic advice for making colloidal silver with a simple home made generator ...
If you are making colloidal silver for regular HUMAN CONSUMPTION ALWAYS use high quality distilled, demineralised, deionised, or R.O. purified water. No exceptions ever! You'll probably have to buy it, but its not expensive. Water from simple 'under-sink' or bench top cartridge filters is not good enough. And never add anything to the water. Do not add salt or baking soda or any other impurity to the water to speed up the process. Increasing the conductivity of the water may dramatically increase the amount of silver dissolved into the water to undesirable levels. Any water that produces white mist soon after the power is applied is definitely no good! Read more about this on our 'Controversies' page.
The following method will at least produce colloidal silver with a useful silver content .
Start with a small clear glass jar - I suggest about 500mls until you become more experienced. (You can increase jar size considerably once you know what you are doing). The electrodes should be kept parallel, about 3 to 4 cm apart, and off the bottom of the jar. For your first few batches apply the power until the water develops a tiny bit of color. This may look silver, grey, pink, or yellow, but whatever color it is it should be almost imperceptible. (Stand a glass of clean water next to the brewing jar so its easier for you to detect the color change). Stir the water occasionally.
The time it takes will vary from about 30 minutes to hours depending on volume, voltage, water quality, temperature, electrode spacing and stirring. Switch off the power as soon as the water begins to change color. If this batch stays nearly colorless or turns very pale yellow overnight its OK to drink - but its not perfect. Ideally you should be trying to produce a batch that has an effective silver content but is clear and colorless. So if all else remains the same (volume, voltage etc) your next brews can be shortened by 5 or 10 minutes each time until you arrive at a brewing time that produces a nearly colorless batch. (But don't shorten it too much or you might have almost no silver in the jar). It takes a bit of practice but water is cheap. And if you make a really bad batch you can still use it as a topical spray. While the batch is brewing take notice of various indicators such as bubbles on the electrode, smoky tendrils falling from the bottom of an electrode or golden trails drifting from the electrodes. Observing and noting the time these appear will help you arrive at an optimum brewing time.
Any voltage from 6v to 36v DC will work fiine but the voltage you finally settle on will probably depend on the jar size and how impatient you are. Just experiment with different voltage until you find one that suits you. (A 12v AC/DC wall power adaptor or a couple of 9v batteries clipped together to make 18v will work fine for most jars).
Higher voltages give a fast result but generally speaking its best to slow the process by using low voltages and keeping the electrodes well spaced. Higher voltages make colloidal silver faster, but lower, slower, voltages make colloidal silver better - this is one reason why the Silver Well automatically, progressively, reduces the voltage from about 30 to 3 volts. Slower speeds also make the process a bit more predictable. The higher the voltage, the further apart the electrodes should be.
A bit of fuzz on the electrodes is normal. It's only the color of the water that's important.
(For more information about ions and particles theres a lengthy discussion at the bottom of the 'Making CS. FAQ's' page.)
IF YOU JUST WANT TO MAKE CS FOR ANIMALS, or external use, you can scale it up. These pics show CS being made in drinking glasses and small jars but you could just as easily use large jars or even a bucket... it will just take a bit longer. And for non human consumption you dont even need to use pure water, but bear in mind that impure water is far more electrically conductive than pure water so you will dissolve a lot of silver into the water very quickly. Be careful you don't over do it.
