Hi , I can get a few copies of this book if there is any interest. This appears to be blue typing but I am not chemist and don't know if there are other non blue print/ferrocyanide type things in it. I know I saw Diazo mentioned in it. Probably in th e45-50 dollar range. If I knew more chemistry I would buy it. I only wanted a simple ferrotype process, so I could make blue paper, and already figured out I bloew it, Ferric Ammonium Citrate is better served with an oxilate. ggrr.
well thats it gotta go ciao chris
