When the particle concentration gets to about 1 ppm, you can see the turbidity (cloudyness).

I have assumed this means larger-than-ideal particles. It is not necessarily true that the particles are larger than ideal, just that there are a lot of particles. In the photo I posted, the particles were measured at less than 30 nm which is smaller than most cs produced. > Frank: have you measured for particle size any of the "milky" sols?

In the photo, the greenish-yellow tinge is the borosilicate glass bottle, not the cs. If you get a yellow tinge, then there is some amount of large particles that are absorbing the blue the spectrum. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
