Some more development on the Niche Gallery proposal.
Test tiles have had first firing in kiln. My sketchbook includes some potential dimensions for the final tiles. Acetates have been prepared for the Lightbox exposure on the trial tiles which have now been treated with photosensitive cyanotype chemicals: Ammonium Ferric Citrate and Potassium Ferricyanide (the latter of which is poisonous). Once exposed and developed, the trials should show the results of positive and negative photo images, as well as negative image of hand drawn images on acetate and tracing paper using a pigment-ink pen.
