Colloidal Silver Color Samples

Here are some color samples I made over the years


80 ppm to 2.5 ppm



20 ppm corn syrup reduced samples. I added 2 drops of dilute corn syrup to bottle A, and 20 drops to bottle B.  Both bottles heated in my microwave for 2 minutes and 30 seconds.  This shows that excess reducing agent does not harm the colloidal silver.

So from left to right, they are 80 , 40 , 20 , 10 , 5 and 2.5 ppm for the top picture ?

Dean:
This is a great help Kephra!
Visual references are really helpful for those who have not had the experience and expertise to say to ourselves, Yep! that's a good'un!
I want to go through a few different ppm's just changing reducing agent and make some comparisons like this myself!

Bravo to you sir! ;D

Dean:
If you're second to left is 40, then Mine this morning is absolutely on the money ! ;D

Yes. 
I made 250 ml of 80 ppm, then took 100ml of the 80 and added 100ml of distilled water to get 40 ppm
Then 100 ml of the 40 was diluted to 20 by adding 100 ml to that bottle...
etc.
