9999 (4N) Ultra Fine Silver is suitable for the production of colloidal silver and solid core mains power cords. Our silver is guaranteed to be 99.99% pure, or better. A copy of the assay certificate will be included with each order.
The Assay Certificate
A 3.1 certificate is issued by an authority that is independent of manufacturing and is validated by the manufacturer’s authorized inspection representative. This is an inspection certificate according to EN ISO 10204:2005 that declares the wire is made of 99.99% pure silver that has total allowable impurities of 100 ppm (parts per million). The analysis was performed using the ICP-OES method.
To protect your silver during transport, we use the vacuum packaging method, which effectively protects the silver from tarnishing/oxidation.

What is Considered Ultra Fine Silver?
Ultra Fine Silver is defined by its purity. For example, silver coins minted for general circulation generally use silver with a purity of between 80 and 90 percent. Sterling silver used in jewelry is 92.5% pure. Thus, silver jewelry is often stamped with number 925.
99.9% (999 or 3N) Pure Fine Silver is used in investment silver production. It is generally considered too pure and soft for industrial, commercial, or jewelry use.
Only Ultra Fine Silver with a purity of 99.99% (9999 or 4N) is pure enough for colloidal silver production. The Royal Canadian Mint also uses Ultra Fine Silver to make its famous maple leaf coin.
