    Hi everyone,

    I am currently studying a new course and have been told that I cant use cyanotype because of the hazards of the disposals of potassium ferricyanide and ferric ammonium citrate. I believe the two chemicals mixed together in the quantities used for cyanotype are safe to use and dispose of. Does anyone know of any evidence or scholarly/scientific articles that can prove its safety to help me out?

    Also look at your local laws on disposal of waste. You may find that you have to take Chem,s to an approved disposal site.
