Cyanotype workshop

Cyanotype is a photographic printing process which creates a cyan blue print. the process uses two chemicals, Ammonium iron citrate and Potassium Ferricyanide, these are then applied to paper or cloth in a dark room until they dry, then place under ultraviolet light and leave exposed for around 8 minutes and wash the chemicals with water, if you want to intensify the blue wash with Milton (bleach) and wash again with water.

I experimented with these pieces first to see if the ultraviolet light would travel through the 5 layers of tracing paper, after they were exposed I could see the layers from the chemicals on the paper but once I washed them away to bring out the blue there wasn’t anything to see, I would need to expose them for a longer period for it to be successful next time.

These were my second attempts, I used two layers of parchment paper which was successful , I didn’t wash these will Milton to intensify the colour.

This is my favourite print, it was a combination of thread, parchment paper and fabric. I would like to experiment with thread further as this reminds me of lighting and it would be an interesting theme for my light project.
