Cyanotype 200ml Kit Cyanotype 400ml Kit

Variant

Invented by John Herschel in 1842, cyanotype is a historical analog photographic technique famous for its deep blue, monochromatic images.
In the 19th century, plant studies, maps, plans (blueprints), and documents were recorded in this way.
This photogram technique is still very popular today.

This is a very simple photographic process.

Development and fixing are done with tap water; a darkroom is not necessary.

With this chemistry set, you can coat and then expose paper or other natural fibers such as cotton, silk, wool, but also wood or leather, as you wish.

capacity

Cyanotype 200ml Kit:

This kit allows you to mix a total of 200ml of cyanotype solution. This is sufficient for approximately 50 sheets of paper or fabric pieces the size of A4.

Cyanotype 400ml Kit:

This kit allows you to mix a total of 400ml of cyanotype solution. This is sufficient for approximately 100 sheets of paper or fabric pieces the size of A4.

Here's how it works:

The cyanotype chemicals are contained as a powder in the two plastic bottles. This results in a very long shelf life during storage.
To use, simply fill the bottles with water up to the indicated mark to prepare the working solutions for approach 1 and approach 2.
A notice: Using distilled water improves the shelf life of the solutions!
Mixing the two solutions yields the light-sensitive cyanotype working solution.
The paper or fabric is then coated with this solution.
Decorate the paper or fabric with objects, stencils, negative templates, plants, etc. as desired. There are no limits to your imagination.
Depending on the template, it can be helpful to weigh it down with a sheet of glass.
Depending on the intensity of the sun, expose to UV light for 3-10 minutes; alternatively, you can use our UV exposure kit.
A chemical reaction takes place where UV light hits the cyanotype sheet.
Wash the exposed sheets with cold water for at least 5 minutes, until the water no longer shows any discoloration.
The exposed areas turn blue.
Within 24 hours, the cyanotype images dry and acquire their deep blue color through oxidation.
To speed up the process, you can optionally add a few drops of hydrogen peroxide to the wash water.

Durability of the solutions

The powdered chemicals in the bottles have an almost unlimited shelf life.
The individual chemicals mixed with water in the bottles have a shelf life of approximately 6 months - 1 year.
Using distilled water instead of tap water improves shelf life.
The mixed emulsion (chemical solution from bottle 1 + bottle 2) is only stable for about 2-4 hours.
Therefore, it is advisable to mix as little as is needed for the current project.

processing

Coated paper is sensitive to UV light --> Ideally, only cover it with objects or foils in rooms without direct sunlight or in the shade.
For sharper outlines, weigh down objects on the paper/fabric with a sheet of glass.
For coating papers or fabrics with emulsion, we recommend our sponge brushes or hook brushes.
You can also use the transparent printing films from Flix Film, Solarfast or Fotospeed to create negative templates.
