Recent Success at Concentrated CS Production
Points Up Requirment of Very Pure, Distilled Water
Only now is the Nepal project generating the appropriate 'colloidal silver'*, necessary to purifier saturation, as per the methodology given to date (and following). Several prior attemps at making the CS failed because the distilled water had total disolved solids (TDS) in excess of the requisite maximum, 10mg./ liter.
* Recent conversation in the internet, 'CS' discussion groups indicates that this term is a mis- nomer. We will continue referring to 'colloidal silver,' as the accepted term, but as ionic, Ag+ in solution, this should more appropriately be called 'Electrically Isolated Silver.'
|The new CS indicates those attributes usually
good quality is achieved: in production a transparent color,
from pale yellow to orange to bright red, and increasingly dark as
per million (ppm) increases. Furthermore, dilution with water
to the lighter colors, back to the orange and finally the pale
As indicated at the bottom of the Erlen- meyer flask, this batch of concentrated colloidal silver is a transparent, dark red.
Where the two prior types of water for which attempts were made were purchased as 'distilled' for the first try and 'de-ionized' for the second, neither gave good results. Unlike the water of the first two attempts, for the third, and successful attempt the water was first tested for TDS, and indicated 7.0 mg. per liter.
Tests for the new colloidal silver have indicated this is 255 ppm. Purifiers subsequently saturated with the concentrated CS that is shown have been inset in sample systems, these given to several humanitarian organizations.
|As to the color of the CS this is a function of particle size
Firstly the color concerns the size of the particle and the way this
light. Upto the point that the first pale yellow is visible the
size of the CS is about 100 nanometers. As color proceeds to
yellow and orange the particle size tends to a maximum of 1.0
Beyond this orange a red is achieved as more and more particles go into
solution. At high concentrations of CS only a bright light
transparency, the solution otherwise appearing as an opaque, dark
A Methodology for Colloidal Silver
This widely replicable process could be put in place in a principal city of almost any developing country, all the resources present in most locations. Mexico is a country where a number of brands of highly con- centrated CS are made and are available, and a similar colloidal silver could be made in most places.
In following this production model it can also be possible to produce concentrated CS for easy shipping within a country. Then the purifiers can be saturated closer to the point of sale, something that would better enable rural production of purifiers. Following is a list of materials and resources needed for an appropriate, low voltage, 27volt DC, concentrated CS generator. After that is a description of the use of the generator, and outputting of the CS.
Please note that aside from the wage of the worker(s) who operate the generator, the primary material cost is for the water, both deionized and mineral free. For the CS produced, at ~170 parts per million, the amount of silver given off at the electrodes is very tiny, no more than perhaps 5 cents (U.S.$0.05) per two liters. So the cost of silver would be negligible.

1. A two liter
with rubber stopper (having three small holes in a row).
HOW TO OPERATE THE GENERATOR
1. Fill the
cookpot with the two liters of deionized water and bring to a
Note that prior to doing this all surfaces, the inside of the pot and
lid and inside of flask need to be properly washed and rinsed several
