Silver Electrodes should not be anodized with a current density exceeding a safe range of about 2 to 10 milliamps per square inch, otherwise large ineffective particles are produced so that for a pair of silver electrodes of dimensions 2” x 6” the current should not exceed 10 – 24 milliamps, or for electrodes of 3” x 12” a current of 36 – 70 milliamperes which we can produce easily with our in-line constant current bulk colloidal generator.
