The colour of colloidal silver
In contrast to the majority of the colloidal silver products, The colour of Crystal colloidal silver is an amber-coloured liquid, it is similar to the colour of dark cooled tea. It is the high concentration of silver particles and not the particle size or pollution, that determines this characteristic colour of Crystal colloidal silver.
Previously, it was the assumption that a darker colour would indicate the presence of large silver particles. This is the case for colloidal silver using other production methods. A watery colour would tell you that it is not colloidal silver, but ionic silver.
The very small particle size of Crystal colloidal silver is confirmed by using state-of-the-art measuring methods which are specially designed for the measurement of particles of this size.
Produced by Malvern Instruments Ltd. in England the High Performance Particle Size (HPPS) instrument is able to measure Colloidal particles with a size of 0.65 nm. The report of the Malvern HPPS indicates that the particles of Crystal Silver have a diameter of 0.65 nm, which corresponds to 19 to 20 atoms. Which is the smallest colloidal silver particle found in any product on the Market.
Depending on the existing atmospheric pollution, the colour of Crystal Silver may change to grey, after opening. This colour change is not an indication of a problem with the product and is not a cause for concern. It has no effect on the efficiency (operation) of the product. The colour change is more often found in and around larger cities.
