Listees, My best guess is that some bottles work for CS storage and others don't, but I suppose this is nothing new. I would imagine that the problem is that it's hard to know the difference between bottles that work and bottles that don't. The fact is that there are many very different, suitable compositions for plastic, so it's easier to just plain recommend glass.
There is a similar problem when it comes to using clear plastic or glass containers to do solar-disinfection/ distillation of water. Exposure to the ultra-violet of sunlight is considered by some to be a viable way of removing pathogens from water, but the problem is that lots of glass and plastic is made with ultra-violet inhibitors, so containers of those compositions are not effective. (Lots of us would get terribly sunburned if automobile windshields/ windows did not have the ultra-violet inhibitors.) Perhaps the day will come when the manufacturer can be contacted to let us know whether or not their container is appropriate to the purpose. Perhaps a bit of consumer research would be in order. Sounds like a worthwhile student project. Reid Harvey -- The silver-list is a moderated forum for discussion of colloidal silver.
