One would think the guy would know the difference between Gold (Au) and Silver (Ag).
What ever the reaction is, or the effectiveness of the end product, I can tell you that a single drop of Hydrogen Peroxide will turn a bottle of colloidal silver completely colorless in just moments.
If all it took to turn large particle ionic silver or colloidal silver into tiny particle more effective silver was a drop or two of H2O2, I have to wonder why some companies have spent up to half a million dollars developing their processes, when all they had to do was make the most basic and inexpensive systems and add H2O2. Something does not seem right to me.
