Gee, just as well you slept on your reply!

I think this is not strictly true. Some silver will remain as ions, but many ions will be attracted to each other under the influence of Van Der Waals force and will aggrigate into larger charged particles. > Sure, if you use a back yard battery project, you may be making silver > crystals!

Again the flocculates are not necessarily large enough to scatter light or appear coloured but are multi-ion particles non the less. These particle are extremely small, much smaller than virus' and blood cells, and actually carry more electrical energy than single ions. > That brings up the heated blasts of it "being a ripoff if it costs over > $40".

When measuring silver ions I make the the TDS factor 0.93 (100 divided by the equivalent weight of silver) which makes 1.08uS/cm = 1ppm as silver.

I have just purchased a conductivity meter with a 1-199 range, and am in the middle of conducting tests vs my silver ion selective electrode. Results so far show a good correlation during clear CS production. <snipped the rest> > Cordially, Fred Peschel Cheers - Ivan -- The silver-list is a moderated forum for discussion of colloidal silver.
