Had my first attempt at making my own colloidal silver today.
12v DC, a cup of distilled water, for eight hours. 999 silver.
Mine turned black, rather than the purple or white I had read to expect.
Is this normal?
The only thing I can think (now I'm posting) is that I should of cleaned the silver with alcohol first. Not that it was visually dirty, but some silver oxide must have been present as it was a couple of "off cuts" taken from my jewellery bench...
Have I just answered my own question?
