Ivan - suppose one used LVDC and an acid solution to produce ionic gold
solution. Are there not chemical reduction methods that might not produce an
acceptably fine gold colloid? I imagine rapid stirring may be needed when
adding, eg, sodium carbonate (just guessing here). Traditional CG has been
made that way I think. It would certainly avoid some of the Frankenstein
HVAC requirements, including it seems boiling the water at times before
completing a run.

regards, Kevin Nolan
