ExeFBM I take great care in washing out the glass jars with distilled water before hand and once the solution is made I just place a cap on it. The only thing in contact with the water at any time are the two silver electrodes, with no apparent Tyndall effect before hand.
I can safely conclude it's just silver.
Edit: I should correct to say, that I fill the jar with distilled water, observe no Tyndall effect, then add the last 1/5th or so from my previous batch. This is to negate the issue of the huge ramp up time and the lack of conductivity of distilled water. The first batch does occur, but like I've said it takes far longer (6+hrs).
