I believe the colloidal portion is expected to precipitate out when frozen, leaving only ionic silver in the solution. Dan

The second to last post from Ole Bob (below) mentions yellow EIS turning crystal clear after being frozen. Anyone try this? Well, I accidentally let a batch run way too long the other day and it turned big time yellow. Filled a liter jug, froze it, thawed it out and it is now crystal clear, been a week and it is still crystal clear meanwhile the original batch seems to be getting even more yellow (darker). I don't know why, sure would like to understand it though.

Brew time was 5.5 hours, Conductance on the next dasy was 18.3 uS/cm and the Ag+ was 13.63 PPM. I filled 3- 1.5 Diet Rite cola bottles. After 24 hours three of then had a slight yellow color, which was probably due to incomplete hot water rinse. The other is crystal clear. I added one drop of 35% H2O2 to two of the bottles and the next day they were sligtly gray. So I remove about ten ounces form each bottle into a 16 oz Solo plastic cups. Both of the bottles and cups were frozen sold and then removed from the freezer to thaw. The thawed product is crystal clear and the Ag+ is now 12.1 PPM and the conductance is 12.9 uS/cm. So when you get off-color EIS (not CS) then do the same. "Ole Bob"
