Thank you Marshall for clarifying the problem. When I used 3 (x9v) batteries to 
make my CS and was too lazy to stirr the solution I did get the black oxides.

Two things happened, the batteries  and my electrodes vanished some how ( I 
suspect some protector of the nation from 90 year old ladie's prosthetics 
and/or two pieces of silver wire :-) )
 I have a Beck purifier  thats not being used ( I have a vague notion that not 
using a useful item is a "sin") I see no reason why it can't be used instead of 
my three, naked batteries. This Beck purifier also uses 3 x 9v batteries for 
its power source, only they are enclosed in a box .
Nice to hear from you.
regards
