James/Robb: Silver is more noble than practically any other common metal. As a consequence, IONIC silver will be reduced to metallic silver and "plate out" on most metal containers. Roger
**Roger, "Plate out"? I can't find this in the dictionary (ok, so I didn't look), but please explain so I fully understand what this means. Also, you say "most" metal containers. Are there metal containers CS can be put into that are okay? I'm assuming surgical stainless is one of them? Thanks for the info. Julie & Critters
