I'm trying to get together the chemistry needed for VDB and unfortunately do not have any printed material on the subject. I am waiting on Christopher James book Alternative Photographic Processes to be available at the library.
I was wondering, in chemical lists I have seen on the web, what exactly is meant by Silver Nitrate. No one specifies whether to use silver nitrate crystals or silver nitrate solution (both are available at bostick&sullivan). If it is a solution, what %? 10-15% silver nitrate? Many recipes indicate the Part C solution to be: xxx(ml) of distilled water + x(gm). I'm assuming when gm is used they are referring to crystal form. My problem with that is no where does the author specify how to dissolve the crystal into the solution. Heat it + stir it? I would like to hear from someone with experience in Van Dyke Printing before I proceed.
