I asked  this before and did not see an answer. When I mix up colloidal 
silver with  DMSO and glycerine, there is a grey precipitation that shows 
up 
the next  day or so. Anyone know why? Or if it is OK to use the mix as is?  
Thanks.

Hi Gayla, I'm don't know why the  color would change...I mix the Brooks Mix 
 for several people. {75%  CS,--15% Glycerin & then add 10 % DMSO.} I have 
never had a color change.  Just the normal heat when the DMSO is added.  
There must be someone on  the list that can give a reason.. I'm curious now 
too..  Lois
