Listmembers, I would like to prepare my own 'Standard Palladium Solution No.3'. Sullivan and Weese (in the 'New Platinum Print') give the followiing formula: palladium chloride 2.3 gm sodium chloride 2.0 gm water to make 25 ml My question is : just good old noniodized table salt? Seems too easy... Thanks in advance, Tom Tom Hawkins portfolios online: http://www.photobistro.com/TomHawkins
