Prabably about the same as CS stored in clear bottles.....that is, a very long time. I have some CS in a glass jar stored in a closet that has been in storage now for about 3 years. The uS reading on my PWT has gone up slightly. It now reads just over 39 uS. I assume the actual total silver content has lowered because the jar shows some plating and some drop out (which is particles dropping/plating out I guess). However the ionic portion has been extremely stable over the years of storage. This is an ongoing experiment in the stability of high ppm clear CS. When I made this batch it measured 37.9 uS, and as I said that was at least 3 years ago.
