The quality of your finished product depends entirely
on the purity of the water you start with and the purity of the silver
you start with. Most of the current literature suggests that only 99.9999%
pure silver can be used. Most home brew systems use 99.9% pure silver.
So, what is the difference? To find out, I contacted Academy Metals, a
company in Albuquerque, New Mexico, that produces commercial silver. The
total allowable impurities in 99.9% (.999 fine) silver is 1000 ppm or 1
part in 1000. These impurities and their maximums are 1) Copper, 800 ppm,
2) Lead, 250 ppm, 3) Iron, 200 ppm, and 4) Bismuth, 10 ppm. This product
is readily available in wire form and costs about $3.00 above the market
(spot) price of silver. When this product is used to make electro-colloidal
silver at a concentration of 5 ppm, the total impurities from the silver
drop to 4 ppb (parts per billion) copper, 1.25 ppb lead, 1 ppb iron, .05
With all allowable impurities at these low levels, there is
a reasonable argument for not being concerned. Still, sometimes small things
make a big difference. 99.99% silver (.9999 fine) has total allowable impurities
of 100 ppm of the same metals in the same ratios, and costs (in wire form)
between $50-$90 above the spot price of silver. 99.999% silver (.99999
fine) has total allowable impurities of 10 ppm, and in wire form costs
about $250 above the spot price. 99.9999% silver, in wire form, costs more
than gold and is very difficult to find commercially.
In one sample of 10 ppm colloidal silver we sent out for
total analysis (made with 99.9% silver electrodes), the primary impurities
found were: 1) Sodium, 470 ppb, 2) Calcium, 260 ppb, 3) Manganese, 70 ppb,
4) Potassium, 50 ppb, and 5) Magnesium, 24 ppb. Since none of these impurities
could have come from the silver, it suggests that the purity of the water
should be of greater concern to the person making their own colloidal silver,
than spending extra money on purer silver.
