i recently brewed a strong batch of colliodal silver between 27 and 28 ppm ,for 
external use  i  allso use it as an aftershave skin conditioner, and even apply 
it to a red scratch on my arm that has been there for agers now its all healed 
and its even matched the tanned skin erea on my arm where its healed, and even, 
a scar from an apendix operation that has been visible for agers is starting to 
fade away to . and i use it under my arm pits and there is no oder what so 
ever,  and i refilled these small bottles with this strong colliodal silver and 
had some left still when i ran out of small bottles so i left it sitting by 
itself in the brewing jar for nearly a week and by itself it developed into a 
golden colour, when i first brewed it i measured a voltage in the colliodal 
silver in the millivolts range which slowly decreased till it got to a certain 
millivolts level the it started to climb again as if there was some electrical 
action going on .   so the charged colliodal silver charge slowly dropped to a 
much lower level after days more of allowing it to sit . before that even 
emptying half the brewing jar the charge measured was still in the high 
millivolts range, this is my second try to post this .as i think it failed 
before.
