Mike, Thanks for making a substantial contribution to the art. Your results using very low current densities and a long "brew" time parallel my own. I, however, make a gallon at a time using currant limiting with as much as 1500 volts. I can't see why the "potential gradient" can have any effect on the end result. I'm not saying it doesn't, I just don't see why it should. What am I missing here? Arnold
