The Science Behind Colloidal Silver

We use colloidal silver around my house for everything from ear infections, to bacterial infections, and find it very effective.  It has saved us many trips to the doctor.  

Today we have a guest post written by the manufacturers at Silver Living Tech, explaining the science behind colloidal silver.

So What’s Colloidal Silver?

Colloidal silver is classified as a metal sol (Good deduction, Doctor Watson!). That means the solid particles of silver are suspended in a liquid medium of water. The particles should range in size from 5nm (5nm = five nanometers = five thousandths of a micron = five thousandths of one millionth of a meter) to 100nm. As with other metal sols, the particles, must be held in suspension through the action of a like-electrical-charge. This dynamic force is only effective if the mass of the particles is small enough that gravity doesn’t pull everything to the bottom. The particles of silver in colloidal silver must be a very pure silver. Often, .999 fine silver is the minimum level of silver purity used in colloidal silver.

What About The Tyndall Effect And Silver?

The Irishman, John Tyndall, was born August 2, 1820.  For a long period of time he was associated with London’s Royal Institution as a renowned physicist with wide-ranging interests.  John Tyndall was best known for his study of light scattering (the Tyndall effect) observed when a light was shined through a specific type of liquid suspension.  In his work, Tyndall noted that some liquid suspensions scattered the light when a light was shined through them, so they seemed to glow.  He also noted that many suspensions didn’t scatter the light. The light passed through without any visible effect.  As he documented which suspensions scattered and which did not, a pattern began to emerge.  In time, he determined there was a narrow band of suspensions in which light was scattered.  These suspensions that scattered the light are now known as colloids.  The stronger the Tyndall effect, the more of the suspension is colloidal.

The Problem with Silver

The problem is, virtually every colloidal silver suspension has some part of it that is not colloidal.  This is especially the case when the Tyndall effect is low to medium.  A low to medium Tyndall effect means more than half (50%) of the colloidal silver is NOT Colloidal Silver.  The silver particles, not colloidal in size, are either molecular (particles smaller than 5nm or .005 microns) or microheterogeneous (particles larger than 100nm or .1 micron).  In either case, the silver particles present a problem.  High concentrations of non-colloidal silver in high concentration dispersions present a real health risk.  A silver toxicity can easily build up.  
So, what kind of colloidal silver should one be looking for?

Stay tuned, next month we will be posting more on that.

    This is fascinating, Jill! I am sharing it, and I am looking forward to the rest of it! I hope you are all well physically and spiritually in the Lord! You are making a difference as a wife and mother first and then as a teacher of other women on this blog.
