The FDA has cleared another silver-based
product. The AlphaSan® antimicrobial additive ( CAS Number: 265647-11-8
) is a zirconian phosphate-based ceramic ion-exchane resin made with
silver, and has been cleared by the FDA as an acceptable food contact
"On surfaces treated
with AlphaSan antimicrobial, bacteria still find their way. However,
they get an extra special dose of silver ions." - Milliken Corp.

Colloidal Silver Production: General FAQ
one tell if a batch of colloidal silver ( isolated silver ) is highly particulate
or highly ionic?
Almost all production methods available for home use produce
both ions and particles in the colloidal silver generation process. In
order to really understand the quality of the finished product, one needs
to have a TEM done ( see our products page for an example ) and tests done
through atomic adsorption spectronomy.
However, one can get a general idea of the composition of
the colloidal silver by using two drops of 35% H2O2 per eight ounces of
colloidal silver. If a thick cloud immediately appears, and spreads throughout
the colloidal silver, then the colloidal silver has a high particle content
- and most likely ( because of the methods available for home brewing )
very large particles. If the colloidal silver remains clear, then one MOST
LIKELY has a high ionic content with smaller actual particles.
Most home generators will produce between 5 - 15% particles.
The idea is to be certain, as much as possible, that the particles that
ARE in the colloidal silver are minute. When the particle percentage increases
in a home brew situation, it is usually LARGER particles being produced.
The colloidal silver from a current controlled generator being used is producing
large particles. 14 gauge + silver is being used, as well as high quality
distilled water, and the batches are being run for less than one hour. What
is going on?
Even when one VERY carefully maintains the cleanliness of equipment, silver
can plate onto the bottom of the glass container being used. Scrubbing
the glass container with a nylon scotchbrite pad helps, but often does
not remove the plating.
The solution is to scrub down the glass being used RIGHT AFTER a batch
has completed using a separate nylon pad with a small amount distilled
white vinegar added. Rinse the glass thoroughly with tap water. Dry the
glass, then scrub the glass container again with a clean, dry nylon scrub
pad. Then, wipe down the container and rinse with a bit of distilled water
Use friction rather than pressure when cleaning the silver electrodes.
Light pressure with fast agitation helps keep the surface of the silver
smooth. Make certain to use a high quality distilled water, such as Walgreens
brand distilled water. Position the silver electrodes as parallel to each
other as possible. Use a heat lamp or a very gentle heat source underneath
the generator to create a slight upward current to help prevent silver
Hydrogen peroxide may also be used to clean any CS production vessel.
Pre-heating the distilled water increases the water molecule activity
and reduces production time. However, there is a possibility that as the
water cools, agglomeration can occur. This would result in larger particles
in the final product.
For special purposes, gradually heating the water to near boiling during
production greatly increases water circulation and helps to prevent "sludge" buildup.
The end product is vastly inferior. However, the increased particle content
can be ideal to make highly volatile and reactive hydrogen peroxide and
colloidal silver solutions. We only use this method, though, with current
How good is the quality of colloidal silver made via the nine volt battery
The quality of colloidal silver made using the low voltage, non-regulated
method is adequate, but nowhere near as high at it could be. The tutorial
provides the foundation for one to explore the principles of colloidal
silver production. The tutorial has not been provided as a recommendation
for colloidal silver production.
