people in the trade use the following terms, as does sota.  another term is 
"coin silver" eating utensils, known as coin silver tableware, which is highly 
collectable. made from melted down old silver coins. usually sterling grade 
(92%)


The silver wires are at least "three nines" pure silver (.999), or better yet 
"four nines" (.9999) purity. The Silver Wires that come with both SOTA's Silver 
Pulser and Silver Maker are "four nines" pure silver (.9999).
NOTE: .999 = 99.9%, .9999 = 99.99%, and .99999 = 99.999%. Do not be fooled by 
manufacturers giving out misleading or false purity claims. Ask for a copy of 
the Assay Report for their silver wires to verify their claims. This is a lab 
analysis of the silver wire's constituents and shows the level of purity.

  Based upon the reality that store bought distilled water is loaded
  with surprising amounts of impurities I don't see any problem with 
  using 99.99% or 99.999% silver. Besides, how does one know for
  sure how pure anything is unless one is willing to spend a lot of
  money in laboratories. Furthermore and based upon a lot of personal
  lab time, it's my opinion that assays are like opinions.
