I made a quart batch that metered at 79uS when done, dropped to and stayed at around 40 uS for about 4 years on the sill.
 I have no idea what the PPM was...probably over 100.
 Crystal clear in the shade, looked like dilute milk in the sunshine.
Eventually something got to it [probably contaminated it when checking the EC reading periodically] and it oxidized into a deep yellow and the EC reading dropped to 30 uS.
 10 drops of H2O2 cleared it up...EC stayed at 30-32 uS, VERY thick TE.
 I no longer have it or the notes, some of this is "ballpark recollection"

... I The second one does not sound right, since one cannot make
45 ppm colloidal silver by proper methods, he had to have been adding
salt, or using impure water...
