Okay, I mixed an ounce of 320 ppm colloidal silver with one ounce of distilled water and then I added one quarter teaspoon of borax and as Kephra said, it didn;t turn gray! So now I have a two ounce spray bottle of what could be a very good antimicrobial looking for a mission to try it on. I think at a quarter teaspoon of borax, this is fairly close to a saturated solution.
My original thought when I first mixed the 20 ppm uncapped colloidal silver with borax, that turned gray, was that one weak aspect of colloidal silver is its light weight mold killing ability whereas borax is a potent mold killer as well as a broad spectrum antifungal as well as an antimicrobial so I was hoping to bolster the mold killing ability of the colloidal silver and possibly have synergy with the other qualities of colloidal silver by adding borax.....like being antiparasitic. I was also thinking that the borax might add to the shelf life of the colloidal silver as it seems that some one mentioned mold growth in their colloidal silver before.
I wonder if the moisture attracting qualities of glycerin would be helpful in this mix?
Now to find something to try it on! Perhaps something like MRSA.
