Cyanotype is a printing process which relies on light sensitive iron salts, giving images a blue tint.

# data[].attributes.body
- 25g ferric ammonium citrate
- 10g potassium ferricyanide
- hydrogen peroxide
- distilled water
- gloves
- two beakers
- paint brush
- large format negative
- 100 % cotton t shirt

- For the first attempt, a major issue was the material type. Silk was used but the liquid wasn't absorbed at all. Cotton seems to be the only material in which the liquid fully seeps through.
- Another issue could have been the plastic pane we used to hold down the large format negative. since it was plastic and not glass, it could have been anti-UV and therefore didn't allow sunlight to penetrate.
- The second attempt was done on paper and much more successful. we used objects such as rocks and leaves, eliminating the use of a plastic pane

- I recommend a thin cotton shirt so the liquid can be easily absorbed and might lessen exposure time
- always wear gloves, these are irritating powders and liquids
- if you wish to use a large format negative instead of heavy objects. use a glass pane to hold it down
- Light colours are preferable for the colour of the t shirt. whites, light or pastel colours work best
- It is a great process for beginners as it is relatively simple and low cost.

The t-shirt is left to expose in sunlight. it was left for approximately 15 mintues. no image was printed on to the t shirt. But this was not a total failure because at least we knew that the chemical process was mixed correctly as the solution was blue, as it should be

Final stage was to coat our fabic in the chemical solution under red light. The t shirt will be coated in the mixed liquid and left to dry.
The fabric is stretched on a board and clamped down to help with even coverage.

Solutions A + B had to be mixed under red light into the smaller cup on the left. Once the chemicals touch it becomes light sensitive which it why it must be mixed in the dark.

(Solution A is the darker liquid on the left. Solution B on the right)

25g of ferric ammonium citrate with 100 ml distilled water. This is solution B.
