Sunprint kits were developed by educators at the Lawrence Hall of Science in Berkeley, California in 1975. The kits are meant to encourage an interest in the photographic process using minimal additional materials, only sun and water, to create images.
Sunprinting is based on the cyanotype process that dates back to 1842. This photographic paper has been treated with a solution of potassium ferricyanide and ferric ammonium citrate which, once exposed to ultraviolet light, causes a chemical reaction on the paper. Objects placed on the paper that eclipse the sun's light will show up in white, with the rest of the paper turning a vibrant Prussian Blue color.
Place a flower (or any small object with an interesting shape!) on the paper, put the acrylic overlay on top of the object and expose it to sunlight. Rinse the paper in water and watch the image appear!
This kit contains (12) sheets of 4" x 4" treated paper and (1) acrylic overlay.
Made in the USA.
