I have wondered with this stand development like Gaglianai used to do where there was a lot of silver in the chemistry, would a slight electrical current accelerate any 'plating' action that may go on. This is a total wild-assed guess on my part as I know squat about chemistry but I have wondered for a while now if introducing a small amount of electricity from, say a 9-volt battery, would help the plating action?
I you think popping your film\dev into the 'fridge would be a kick, how about plugging it in and coming back in 8 hours<g>?
Any ideas about the practicality of this? I'm sure someone, somewhere has tried this...
