Apparently there is a difference between the LVDC and HVAC method. The particle size increases when the electrode area increases in the HVAC process. I believe that the sputtering of the particles is accomplished primarily by OH radicals in the LVDC process and by free electrons in the HVAC process. This might account for the apparently opposite effects. Marshall -- The silver-list is a moderated forum for discussion of colloidal silver.
