I found you while looking up salt prints! I am wondering if you still are making them and if you can help me. How can I tell when the silver nitrate solution has gone bad? xlf@sbcglobal.net
hey!! sorry for the delayed response... but in answer to your question, i'm not sure there is any particular way to tell when it's gone bad. since it needs to stay in the dark, you can't really tell if it looks different. over time it definitely loses it's potency, though. i also responded to your comment on my blog with a little bit more detailed answer. hopefully it will help you :)
