Re: RSG-2, Colloidal Silver made at room temp is grey instead of gold.

bought a silver pulser from Sota Instruments can get a cheap model for $115 I got the better one, but make 16oz at a time and it takes 2 hrs and is clear if you leave it longer it gets to light yellow then amber, if that happens (if i forget I'm making it lol) I just use it as a disinfectant on my counters and sinks etc.

It can also be used for dandruff control by spritzing the head after shampooing and leaving it in.
