Brown???  It shouldn't go brown.  Brown is something I would be looking further 
into.  That container may not be suitable?  Maybe it's developed more 
particulate silver?
Probly still good to use, just may be higher in particulate content.
When I go away I just use one of those clear plastic bottles you buy water in.  
I put it in the boot of the car, or on the backseat somewhere while travelling. 
 Not in direct sunlight, but it's still exposed to much more sunlight than it 
would be in a cupboard in the kitchen, but it never goes 'brown?'.

Subject: CS>odd situation

Hi, I was wondering if someone can help?  About 6 weeks ago I made some CS to 
take with me on a trip.  I made it with a silver puppy and it was perfectly 
clear and seemed potent.  I put it in a Rubbermaid plastic water container and 
carried it with me.  After about 3 weeks on the road it turned a brownish 
color.  Can anyone tell me why this happened and if it is still good to use?
Thanks. PT
