Dr Robert Beck produced some information concerning Colloidal Silver and making your own, and this info along with other protocols for blood cleansing are shown
here.
The information page on making your own Colloidal Silver is at
this page.
I have been making my own for some time now, and use a simple setup using pure Silver electrodes which can be purchased very cheaply from
Silver Well at just A$20.00 pair of electrodes
"9999+ Silver 18cm Straight Electrodes........$20 a pair
For simple home-made D.I.Y. generators or some other brands of generators. (Not suitable for use in Silver Well generators.) Straight 7" (18cm) 12 gauge .9999 silver electrodes for $20 a pair. This is top quality wire, thicker than the 14 guage wire you'll usually get elsewhere.
Postage for electrode sets is FREE in Australia, NZ, and Pacific. When ordering electrodes use your normal postage address."

Hope this info helps, there is a lot of info out there on the net about it, and no you WILL NOT TURN BLUE with Colloidal Silver.
