Variant

Cyanotype, invented by John Herschel in 1842, is a historic analogue 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 the help of this chemistry set, you can coat paper or other natural fibers such as cotton, silk, wool, but also wood or leather and then expose them.

capacity

Cyanotype 200ml Kit:

This kit allows you to mix a total of 200ml of cyanotype solution. Enough for approximately 50 A4-sized sheets of paper or fabric.

Cyanotype 400ml Kit:

This kit allows you to mix a total of 400ml of cyanotype solution. Enough for approximately 100 A4-sized pieces of paper or fabric.

This is how it works:

The cyanotype chemistry is contained in powder form in the two plastic bottles, ensuring a very long shelf life.
To use, simply fill the bottles with water to prepare the working solutions for batch 1 and batch 2.
A notice: Using distilled water improves the shelf life of the solutions!
By mixing the two mixtures you get the light-sensitive cyanotype working solution.
The paper or fabric is then coated with this solution
Cover the paper or fabric with objects, stencils, negatives, plants, etc. as desired. There are no limits to your imagination.
Depending on the template, it may be helpful to weigh it down with a glass pane
Depending on the sun intensity, expose to UV light for 3-10 minutes, alternatively you can also use our UV exposure kit.
Where UV light hits the cyanotype sheet, a chemical reaction takes place.
Rinse 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 receive their deep blue image tone through oxidation
To speed up the process, you can optionally add a few drops of hydrogen peroxide to the washing water.

Durability of the solutions

The powder chemicals in the bottles have an almost unlimited shelf life.
The individual chemicals mixed with water in the bottles have a shelf life of about 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 not to mix more than is needed for the current project

processing

Coated paper is sensitive to UV light --> If possible, only cover it with objects or foils in rooms without sunlight or in the shade
Weigh down objects on the paper/fabric with a glass plate for sharper contours
For coating paper or fabrics with emulsion we recommend our sponge brushes or Hake brushes.
To create negative templates, you can also use the transparent printing films from Flix Film, Solarfast or Fotospeed.
