I noticed in several of the past posts some references to the color of CS
produced by various methods under various conditions. I found this narrative
on the subject by Zane Baranowski, C.N. in his book, "Colloidal Silver - The
Natural Antibiotic Alternative", copyrighted 1995 (cost of the booklet back
then was $3.50) I hope Zane won't mind me extracting a short quote in exchange
for the plug on his booklet. BTW, Zane is a certified nutritionist from the
National Institute of Nutritional Education in Aurora, Colorado.
from page 10 ....
"One indicator of the quality of colloidal silver is its color. As the
size of each silver particle gets larger, the color of the suspension ranges
from yellow (best) to brown, to red, to grey, to black (inferior). The
increasing size of the particles also reflects a proportionate decrease in
quality of the product. Colloids of silver that are produced using the
electro-colloidal method are a different color than the grind or chemical
method forms of colloidal silver. That rule generally applies, except in the
case of some brands that use an artificial yellow dye to falsify the proper
color. Color variance also depends on concentration, stabilizers, and the
presence or absence of other trace elements. The ideal form of colloidal
silver will be almost colorless or have a very light yellow color. Besides
buying from a reputable company and visually checking the color of the product,
another quick way to see if a solution contains colloids is by observing the
Faraday-Tyndall cone effect. When a sharp and intense beam of light passes
through a colloid solution. the path of the light will appear to be turbid.
The path of the light is also altered. The path of the light will form a cone
shape within the solution. The best way to observe this is to take a test tube
of colloidal silver into a dark room and shine a very bright flashlight through
it. Colloids will appear to be milky. (Note: a discussion can be found in
Jirgensons and Straumanis' book titled "A Short Textbook of Colloidal
Chemistry;" New Yorkk: John Wiley & Sons. Inc.; London: Pergamon Press Ltd.;
1954)"

Nice to know that we are all tracking down the pale yellow (almost colorless)
electrical road with our super-fine silver particles in the range of 0.005 to
0.015 microns in diameter, suspended in pure water without the need of any
chemical, stabilizer, dye or other ingredient. Good ... works! Share the
goodies!
Best of health to all,
