Colloidal Silver Color Samples
« on: January 22, 2017, 07:12:51 PM »
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.




20 ppm corn syrup reduced



Gelatin Capped Silver Dilutions.
Left to right: 320 160 80 40 20 ppm

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

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.

When I get a chance, I will make a serial dilution of 320 ppm gelatin capped.  I managed to find 5 identical bottles so I can do 320 160 80 40 and 20 ppm.

the top picture is that after reduction?
also what method. sugar always seem to darken the mixture after heated.
been using this site quite a bit to get me started on silver nano colloids. (10-20nm) been very helpful going into the chemistry and all. thanks.

Since ionic silver is clear, it has to be reduced silver.
It was made with maltodextrin.

Very nice, Kephra!

That is what I have come to expect of the batches I make based on starting with 320 ppm. ;)

I notice quite a color difference between the 20 ppm in the top picture and the 20 ppm in the bottom picture??

Yes, gelatin makes the color darker.
