Nice post Bob. Concerning Tyndall effect .
The Faraday - Tyndall cone is a property of colloidal systems with particle sizes greater than about 1nm (0.001um), whereby a beam of light when shone through a colloid will be scattered off the colloidal particles and be seen as a beam (reverse cone). Much as a flash light shone through smoke. With particle size of 1nm the beam may be too faint to see. With particle sizes less than this visible light will not be reflected, and the system can be classified as a true solution. A small laser pointer can be used to test for the 'Tyndall Effect' (which is slightly different to the beam effect) and can give some information as to particle size and/or concentration of CS.
