Making Cyanotype Prints : Cyanotype Developing Tips

[SeaShipDev]

Cyanotypes use a solution which contains cyanide, thus the name cyanotype.

It uses: Ammonium iron(III) citrate: Potassium ferricyanide.

The peroxide is just a speeding process. The print will naturally turn dark blue as it dries.

yup your right it has cyano is not cyanide. It's the color cyan, but id does give off hydrogen cyanide gas. If you ever took a alternative process class, you will be warned about it. Plus if it mixes with a VanDyke mixture you could die.

From greek kyanos it just means "blue" and has nothing to do with poison, compare cyanos.

Bullshit, has nothing to do with cyanide (except you mix with very very strong acid) (And since when kids have had them?)
