After stirring the salt solution for a minute, pour some of the water into an eye dropper bottle. Now you're ready to make Colloidal Silver. Pour eight ounces of distilled water into your glass. If you use too much salt, it is possible to make silver chloride as well. Silver chloride is by definition the precipitation of salt crystals within the solution which fall to the bottom of the glass.
Silver chloride produces ionic silver, a non-toxic germicide similar to colloidal silver.
Insert silver electrode wires. Placement of wires is not critical, but they must not be touching each other or the process will stop. Laboratory tests show that this method creates a silver colloid of approximately one ppm per minute of activation time. Since you are taking only microscopic particles from the silver wire, your silver wire may very well last for years. The brightness of the light bulb is related to the conductivity of the water.
