This week in forest school, Year 6 pupils made cyanotype prints (sometimes known as sun prints). Cyanotype is a photographic process that produces dark-blue prints. The light sensitive chemicals used react slowly to UV light.
Once handed the freshly painted paper, pupils carefully laid leaves on it, a sprinkle of turmeric (for a golden glow) and then a couple of squirts of vinegar (for luck). They had to work quickly because as soon as the paper left my dark room (Mrs Pearman’s shed), they began to react with the sunlight outside (and it was a very sunny day).
The prints were ready to wash with water when they took on a brownish tone. I love these! Please view the results in our gallery below:
