Dot; Basically to make good CS one needs to control the elecrode spacing, wet length of the electrodes, ans use constant stirring.
There are generally two system types used; constant voltage and constant current. Each requires it's own set of cut-off paramters. CONSTANT VOLTAGE; Uses batteries or a power supply that has a fixed voltage, and the current in the brew cell is monitored with a digital multimeter in one lead of the cell. For a small amount 8 to 16 ounces with two #14 silver wires as electrode the shut-off current is between 3 to 4 ma. for larger amounts of DW then then current must be adjusted for the increased electrode surface area. CONSTANT CURRENT; This uses a fixed power supply of 27 to 40 volts (can be higher) but in one cell lead is placed a semiconductor unit that is wire as a constant current source. This reduces the cell voltage by limiting the cell current until the current reachs the set limiting value. At that point the current stays constant. In both systems constant stirring has been proven and has now been added to all of the commercial units. Bubbling of air through the CS does not supply the velocity between the electrodes to stop agglomeration of the silver particles. This can de demonstrated with the laser pointer. It shows up in the brightness of the Tyndall beam. The brighter the beam the larger the particles and we do notwant that. In fact the very best CS will have no T.E. I hope this help answer your questions. If you have more send them. Also visit the archives for aditional info. I appreciate Dr. Jon's input even if it is antiquated. It is making more people aware of CS. Remember he is an M.D. and so wemust allow him some leaway :-) "Ole Bob: -- The silver-list is a moderated forum for discussion of colloidal silver.
