Hello, 
I have just come across this site & been reading the letters for about 2 weeks. 
I am wondering if it OK to heat silver water to make tea with it?
Also, I am interested in this testing that Bob talked about.  I am always 
curious about the silver content in my water?  Is this what he is testing?  How 
can I send samples, and where do I send them?
Thanks for your help.
