 1. Silver  oxide  produces the yellow tint in  cs,  and  adding H2O2
 produces a clear solution. If the H2O2 generated silver oxide as you
 propose, the  solution  should  become a  darker  yellow,  don't you
 think? Here's an equation that may be useful:


Why do you say that silver oxide makes the yellow tint? Yesterday I had a
saturated solution of silver oxide, and it appeared crystal clear.  I will
test again, but I don't think silver oxide dissolved in water has a yellow
tint, it is does, it is certainly very light.

The yellow tint is caused by particle size. This was proven over 100 years
ago, and all tests since then confirm it.  If it was silver oxide, how can
you explain that it goes to gold, then orange, then red as the particles
increase in size?




Here's another thought you might explore:
Try reducing a batch until it turns from clear to a noted color, then add back in the exact ( as well as can be determined) amount of distilled water that was removed. Now you should have a clear solution. That kind of flies in the face of the above statement that color is caused by particle size. Wouldn't the color remain if it was caused by particle size? Adding water would change the concentration, not the particle size. I use a well cleaned coffee carafe on a coffee maker hotplate and never let it get below half full. I can go to a deep honey brown and bring it back to clear. I've done it a couple of times just to experiment.
  I use the concentrate to make a gel or mix with aloe for topical use.
It doesn't plate out in a reasonable time ( couple of weeks) until I use it.
I have no idea how many ppm I have but I actually get a slight buzz when I drink some. I don't know how they made their determination 100 years ago but they didn't have Mr. coffee to work with.
