Today, I observed another change in the 1st batch of colloidal gold. The metallic surface particles observed earlier were not present today. But floating within the liquid were large, filamentous, floating aggregates some as large as 10mm in length. They did not appear metallic. I filtered the colloidal gold through a coffee filter and spread the filter paper flat across a double layered paper towel. I used a 8X loupe to magnify the material. Within the approximate 4" filter diameter there were more than 30 groups of dark, micro, hair-like aggregates along with some other dark, non hair-like particles. The hair-like groups were splayed together very much wet head hair.
As I am scrupulous in my glassware cleaning, I am certain I did not contaminate the liquid during any of the processes. Ditto for equipment and ingredients with the exception of the salt which had sodium silicate anti-caking agent in it and the Carbo-Gain. Anyone experience anything similar?
