I have never heard of glycerine use either. But I have heard of using small amounts of organics in some refining cells.

Some years ago I set up an electrolytic cell to refine Indium. My anode was 98% In and the electrolyte was 100 g/l In in nitric. The In would not plate on the cathode correctly, it would make a mud that would just slide off.

After reading some more I found a reference to organics added to the electrolyte, but no exact reference as to what. I tried several things, some worked better than others. Eventually, adding 1 g/l of wood glue gave me a nice hard In plate, not unlike gold from a gold refining cell.

I never did set up to refine Indium on a large scale.

I know of other uses for organics in silver refining cells.
