I've been using a bar anode at 15mA for so long I forget what the limitations are for other anode sizes. However, it seems like no matter how carefully I try to clean everything, my IS always takes on a yellow tint, meaning there's still some reducer somewhere (cold process).
My next plan is to use a fresh wire anode & cathode pair in fresh glassware.
Will 15mA still work with a wire anode & strong stirring? I've been spoiled by the speed of the high current. (Thank you again Kephra for the SilverTron Elite!)
For reference, what are the general guidelines for current v. anode size, effect of stirring, etc.?
