mraluma415,
Thank you for your suggestion. In this case, however, I stored the ionic silver in both a clean, plastic bottle and a clean, glass jar. The ionic silver in both containers changed to the same clear yellow. When I made the ionic silver, I did not use any Karo syrup and the beaker I made it in had never been used before (it was the very first batch I had ever made). I'm quite certain there were no contaminants introduced into the ionic silver. Any thoughts?
