One of the easiest ways to distinguish the quality of a colloidal silver product is to look at the colour of the liquid. Not all colloidal products are the same; therefore this article will give an overview of the colour characteristics of the different types of products.
Most products advertised as “colloidal silver” contain mostly silver ions, not silver particles, therefore they are silver solutions, not silver colloids. Ionic silver solutions contain mostly silver ions, not particles, so technically they are silver solutions. Products manufactured by electrolysis are typically ionic solutions. Even though the product may have the word “colloidal” or “nano” on its label, it may not contain any silver particles at all. These products are clear, tasteless, and look like water. The majority of these vendors claim that their products are photosensitive and must be stored in dark, glass bottles. Furthermore, electromagnetic fields influence ionic silver, not real colloidal silver. If the product is reactive to electromagnetic fields from the TV, radio, etc., then you can safely assume it is an ionic silver solution.
Silver protein products are the second most prevalent type of so-called colloidal silver products on the market. These products consist of a combination of metallic silver particles and a protein binder and can easily be produced by simply adding water to silver protein powder sold by various chemical companies. Silver protein products generally have very large silver particles, so large that they would not remain suspended as colloidal particles without protein additives. Their color ranges from light amber to almost black with an increasing concentration of silver. These products tend to have a concentration ranging from 30 PPM to 20.000 PPM. Some of them may be labeled “silver protein” or “mild silver protein”, most of them will be labeled as “colloidal silver”. If you are unsure of the color and PPM of the product, an easy way to ascertain if it is a silver protein is to shake the product in a clear bottle for a couple of minutes. When shaken, a silver protein product produces foam above the liquid that will persist for minutes after being shaken. This is probably the single most reliable indicator. Even when the product label identifies the product simply as colloidal silver and never mentions the word protein, this indicator will signal the presence of a protein binder. Shake the bottle and look for foaming. When the foam persists, protein is present.
Crystal Colloidal silver water is a clear, amber-colored liquid that resembles iced tea. It is the very high concentration of particles, not size or contamination, that gives our colloidal silver its distinctive coloration.
Previously it was assumed that the dark color would indicate the presence of large silver particles. This is the case for colloidal silver where other production methods are used.
A watery color indicates that it is not colloidal silver, but ionic silver.
The very small particle size of Crystal colloidal silver is confirmed by using the most modern measuring methods, specially developed for measuring particles of this size.
The High-Performance Particle Size (HPPS) measuring instrument, produced by Malvern Instrument Ltd in England, is able to measure even colloidal particles with a size of 0.65 nm. The Malvern HPPS particle report indicates that the Crystal Silver particles have a diameter of 0.65 nm, which corresponds to 19 to 20 atoms. This makes these particles the smallest colloidal silver particles in any product on the market.
After opening, the color of Crystal Silver may change to gray, depending on the atmospheric pollution present. This color change is not an indication of a problem with the product and is not a cause for concern. It has no effect on the effectiveness (operation) of the product.
