Argyrotype Process

 Argyrotype is an iron and sliver based UV process and was recently invented Dr Mike Ware. this process is by far my favorite because it has a width range of tones as well as having great contrast.

Ingredients 
-argyrotype solution
-paper (acid free)
-sodium thiosufate
-glass rod or hake brush
-pencil
-sticky tape
-negative film

Print
( Note: Don't let the Argyrotype come in contact with metal.)

step1: Tape the paper to a work table

Step2: Mark out film position on the paper.

Step3: Coat paper with Argyrotype solution using a glass rod or hake brush then dry the Argyrotype solution

Optional step: this is when you can change the tone of the pre coated unexposed print by placing it in a steam. (sample at the bottom of the page).

Step4: tape down the negative over the Argyrotype coating.

Step5: Expose Argyrotype in a UV unit or in the sun.

Step6: Then develop.

Note:if you decide to guess the exposer instead of using the test strip method, the exposed print should look about 1 stops overexposed before developing because the image will wash out a little  

Process baths

Bath 1: develop, distilled water (10mins)

Bath 2: clearing,distilled water (2mins)

Bath 3: fixer, 2%sodium thiosulfate and distilled water (2-3mins)

Bath 4: wash,running water (30mins)

Dry





Here is a rough guide to cheaply tone Argyrotype prints


Before applying the Argyrotype solution soak the print in warm / hot water then hung to dry but when the paper is damp not wet apply the solution. After applying solution ,dry the surface with a hair dryer then place the unexposed print in a steam bath for 20 minutes. After 20 minutes remove the print and place the print between two layers of clear film to stop the moister from escaping then expose the print as normal. 


After applying the argyrotype solution, dry the solution with a hair dryer then place the unexposed print in a steam bath for 20 minutes. After 20 minutes remove the print and place the print between two layers of clear film to stop the moister from escaping then expose the print as normal. 


After applying the argyrotype solution, dry the solution with a hair dryer then place the unexposed print in a steam bath for ten minutes. After ten minutes remove the print and place the print between two layers of clear film to stop the moister from escaping then expose the print as normal.
