To buy a large bottle of brown glass in which to store CS, go to the health  
food store and buy the cheapest item in a gallon brown glass 
container--probably  aloe vera juice (about $6).  You can use the juice, or 
pour it  out.  If 
you were to find a supplier of the brown glass bottles, you would  probably pay 
$30 or so for that size bottle.  I found a supplier of the  pint brown glass 
bottles; they wanted $20 apiece.  That is why I just buy  the bottle with 
something in it, and throw out the contents.
