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. Respectfully, Rich Adams ----- Original Message ----- From: Robert Berger To: silver-list Sent: Friday, June 16, 2006 10:20 AM Subject: CS>EIS & Agglomeration Greetings, I made two gallons of EIS using the assymeterical electrodes using 33 volts DC. 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"
