hello,
I made 320ppm 1000ml,15mA 320minutes, heat and gelatin reduced/capped constant stirred. after i moved the 1000ml 320ppm to another jar, this is what i found. what is this left over in the jar, stuck to the inside surface of the jar as well as something black at the bottom.


Thank you

Probably silver oxide fall-out due to too high current or not enough stirring.

Even with lots of stirring, I always get amber residue on my glass after a long run. 1 litre of 200ppm at only 5mA takes 10 hours.

I think the high heat coupled with many hours of exposure is the culprit here. But that glass looks more dirty rather than colored.
