Hi Jill,
   
  What method are you using to test for silver concnetration?
   
  The silver "sticks" are called wires when ordered. When used to brew with the 
are called electrodes. :-) A minor point of infromation.
   
  If you would like a pre-issue copy of my booklet, you might find it useful. 
Its free!!
