Re: [pinhole-discussion] silver, copper and fixer deposits
eric, you can remove the silver from used fixer with copper... some folks use sheets of it the silver copper happily trade places, it's not really an attack... don't know about the other process you have in mind, though jim Many thanks, Jim Kosinski Starlight Cameras PO Box 540 Cherry Valley NY 13320 usa Merlin pinhole cameras darkroom kits www.paintcancamera.com 607-264-3480 ---BeginMessage--- Hello all, Is is possible to use copper scraps to plate out silver from spent fixer? There seems to be a mild attack on the copper if it is placed into spent fixer. I am almost tempted to try copper plate etching for intaglio printing plates using the fixer as a mordent. I am have held off due to the potential of other by-products... my knowledge of chemistry is really rusty. Is there anyone on the list with chemistry hints, or a resource book that can steer me in the right direction.

Re: [pinhole-discussion] silver, copper and fixer deposits
Hi: I read somewhere that copper used in one of the 3 common solutions in the darkroom causes sulpherdioxide gas wich causes headaches, drowsyness, and other side effecs. Why don't you e-mail Ilford's saftey people? They're nice. Dean Hello all, Is is possible to use copper scraps to plate out silver from spent fixer?
