The Photographer's Formulary New Cyanotype Printing Kit was formulated by Dr. Michael Ware. The formula was established in the Jan/Feb. 1997 issue of Photo Techniques.
According to Dr. Ware, The "New" Cyanotype process uses a single sensitizer solution, having a long shelf life, to make prints of an excellent stable blue color and a long tonal response, and with a speed much faster than the traditional process."
The" New" Cyanotype kit also loses little, if any, blue color in the final wash water, and is much more suited to a greater variety of papers.
This kit will produce approximately 50 - 8 x 10" prints if the sensitizer is applied with a glass coating rod (makes 100 ml (3.3 oz.) of solution).
Note: Item requires the use of mortar and pestle and 4 oz jug (none are included)
