    I checked out your photo on flickr...ok I guess. Alan Greene is teaching this fall at the ICP in New York so you might want to go and do the workshop with him. We made callotypes with him but he had already prepared the paper and we made the exposures...none were as good as the negative I brought with me and then printed with salt...that's what I do now...we have the advantage of using film so I do
    good luck with your quest; Peter

    Here is my recipe: I must credit Wikipedia for most of it, but I had to play with the instructions to get it to work.

    Chemicals needed:

    Iodized paper
    solution A: 6.5g Silver nitrate
    170ml distilled water

    Solutioin B: 57g Potassium iodide
    1000ml distilled water

    Sensitizing solution:
    6.5g Silver nitrate
    57ml distilled water
    10ml Glacial acedic acid

    Developing:
    1g Gallic acid
    100ml dilstilled water

    To make the iodized paper I used a Buckle brush to apply solution A. Blot the paper dry, then place, face down, in solution B for 2-3 mins. Blot the paper dry, then hang until completly dry. This first process was done in open light.

    To sensitize the paper I again used a Buckle brush to apply this layer in a darkroom with safelight. I actually used a candle and it worked fine. I then blotted the paper dry, and hung it up until it was fully dry. At this point I made two exposures in bright open shade. 1 min was a bit over exposed, so you will have to play with the exposure times.

    I then processed the paper by mixing 1 part sensitizing solution with 1 part processing solution. I painted this on the paper until I got my image. I washed this in water for about 10 min. then fixed in a very dilute solution of Ilford rapid fixer for about 10 min. About 1 tablespoon to 1 liter.

    I will tell you that the image I got was not a great one, however there is a good image. The problem was in adding the different layers with the Buckle brush. I need to learn how to do that and make a nice even layer. Streaks appeared on the paper that were very bad because of my inconsistant application.

    Hope this helps.

    Why not use a glass rod (a.k.a. puddle pusher) instead of the buckle brush?

    Take a look here:

    The puddle pusher works very simply. The solution to be coated is dispersed in front of the glass rod. The rod and the puddle is then pushed across the paper. The action can be reversed coating in the opposite direction. Any excess coating may be wicked up with a paper towel.

    I like the looks of it, and its cheap enough. Does it drag across the paper or roll? My only concern since I work with some very thin vellum rag paper.

    It's best to think of the puddle pusher gliding over the paper surface. The glass rod is a hollow tube and the ones sold by have a glass handle fused to it to make coating easier.

    You can coat vellum with it just fine but you wil probably wish to tape the paper down.

    I have a large piece of plate glass covering my counter in my darkroom. This provides a clean rigid surface to coat on and can be cleaned when necessary.

    Coating paper with a glass (or acrylic) rod works well with papers that doesn't curl / become wavy excessively, when they get wet. Very thin papers could pose a problem... You have to try and see if that works for you. If you have a neon sign maker nearby, maybe you can persuade them bend a small scrap tube to bicycle handlebar shape, and use that as the puddle pusher - I have several tubes (4" - ... - 13") made this way...

    Regards,
    Loris.
