Hm, so the sol is supposed to be colourless then? Interesting-- I've heard conflicting opinions on the subject, but if you're scattering coherent light then yeah, you've got a colloidal sol. I think that I might have to hack together some sort of apparatus so that I can do some proper testing and see where this material actually lies on the activity spectrum. It would be interesting to see the soluble silver content over time, as well as the stability of an unprotected sol over time. We've got a really handy model for antimicrobial activity as a function of silver release, so that'll tell me a lot.
All I'll need is a bit of 9999 silver. An ounce'll do nicely-- I can make the electrode from that easily. Any volunteers?![]()
The last batch I saw was mostly clear with a slight yellow/brown hue. I'd send you some but my fiance probably wants me to spend our money on bills or something lame like that :D Would old, almost used up silver work?
