It's a true metallic colloid and will oxidize into a blue grey sediment in a few weeks.

Hi Dan,<<<<
Interesting work. I have seen similiar work for silver using math to arrive at a PPM designation.
But my question is how can we account for the formation of oxides i.e Ag0 or Cu0?
Tomorow I will order the chenicals to go with my spectrophotometer to measure the Cu+1 ion.
I will have to find a standard to measure against as I have for the silver ion.
Next question for what and how do we use copper hydrosol.
