Constant current power source or computerized generator.
A fixture to hold your electrodes.
Mix up the corn syrup with an equal amount of distilled water. This will be the reducing agent which converts ionic silver to true colloidal silver. Make 1 or 2 ounces, as you will only need about a teaspoon of this mixture per gallon of water.
Insert your electrodes into you fixture and then into the water. Turn on the power. Put as much of your positive electrode into the water as possible, and no more than 1/4 inch of the negative electrode to start.
Using a milliammeter, measure the current through your electrodes and if the current does not reach the set point of the regulator, you can insert more of the negative electrode into the water to increase the current. If using silver wire for your electrodes, your current regulator should be set to no more than 6 ma. If using a 1 ounce bullion coin, it should be no more than 15 ma. These currents can be increased if you have a sufficiently strong stirrer.
When the required time has elapsed, turn off the power, remove the electrodes, and add 4 drops of the corn syrup solution to the water and heat it to at least 140 degrees F. In a few minutes, it will change from crystal clear and colorless to crystal clear but yellow colored. This color change is the proof that the ionic silver has been converted to true colloidal silver.
