Robert, I'm using the brown bottles to store the colloidal silver in. My instructions say that brown or cobalt bottles stop ultraviolet light. And I have a brother who was involved in photography for years who tells me that even some indoor lights can give off some ultraviolet rays.
I never seem to have anything falling out of suspension. Thanks for explaining about the laser pointer. > Richard, > > Junk the brown bottles, and use clear 16 oz coke bottles.
