What Is Colloidal Silver?
A colloid is defined as very small, finely divided solids (particles that do not dissolve) that remain dispersed in a medium for a long time due to their small size and electrical charge.
In this form, which is elemental (not a compound), the silver is most readily assimilated. Before anything can be utilized by the body, it must be converted to a colloidal state. Colloids range in size from 1-1000 Nanometers.
In order to be classified as a colloid, the substance in the dispersed phase must be larger than the size of a molecule but smaller than what can be seen with the naked eye.
One property of colloid systems that distinguishes them from true solutions (ionic silver or silver solutions) is that colloidal particles scatter light. If a beam of light passes through a colloid, the light is reflected (scattered) by the colloidal particles and the path of the light can therefore be observed. This is known as the Tyndall effect.
Mr. Searle writes, “The dispersed or suspended particles are not merely so minute that the effect of gravity on them is counterbalanced by other forces which keep them in suspension (though they are often only one-thousandth part of the size of average bacteria), but they are in a state of unordered oscillation which gives rise to the well-known Brownian movement.”
