Here is a message that causes concern.

 I asked her where she read this.  Someone on the list may know.

 See what you think is a good answer for her.
Maybe a link or two would be in order.

=====================  Question on PPM
Hi

I hate to post a question...but....,

I have a question about Collodial Silver that we most of us make.

I read a pretty good article about how it should be :
...........yellow brown color
......500ppm using 99.(% silver)....

It stated that most "homemade" is about 3 - 30ppm .....

It also stated that CS needs to be at
least 250ppm to show effectiveness in order to
disable a pathogen's (prokaryotic) oxygen-metabolic enzymes.
{ 500ppm is best ??? }

I bought my 99.9% uncirculated silver bars from the
US mint.......but my CS is clear??

Am I doing something wrong ???

Thanks,
Kem R.,  ND
