Does anyone have any knowledge of any other double salts of elements which
can be reduced by ferric oxalate and u/v light apart from the usual
silver,pd/pt and gold?
I did a quick experiment with cobalt chloride a few months ago and got a
weak purple but otherwise useless image.
I would be pleased to hear from anyone out there with information about
copper, cobalt, nickel et al....but not the rarer noble metals....my budget
won't run to iridium, osmium, and rhodium!
