: : Not so fast. Where does Kodak say "metal" toners do not offer protection? and some references: http://www.usask.ca/lists/alt-photo-process/2000/jun00/0427.htm (note something that's not mentioned in this article, Kodak selenium toner has a high content of fix, something few people seem to know even though it's mentioned on the label) see article by the Image Permanence Institute (IPI) http://www.clir.org/pubs/reports/dirsci/dirsci.html http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=003T6K on the gold toner issue, from experiments at RIT?s IPI: http://unblinkingeye.com/Articles/Archival/archival.html "Perhaps the most shocking discovery of the past couple of decades has been that the noble metals in many popular toners do not always provide adequate protection for silver images. Silver is only protected from oxidation to the extent that it is completely replaced or plated over by a more stable element (gold, platinum, or palladium) " there's more but I can't put my finger on the ref's at the moment. btw, I also run my own tests and always advised my students to do the same rather than believe everything one is told by photographers, lecturers (including me) or reads, especially when one purports to expound on facts. Oddly, there are people out there in the world who seek glory or gold at the expense of truth, something I've never quite come to understand.. k (only the facts ma'am)
