Re: Cyanotypes

Hello Colin,

I use prepared cyanotype papers as well as sometimes coating papers
myself.

Cyanotypes will continue to darken for a while after processing. You
can speed up this darkening process by using hydrogen peroxide from
your druggist. Be sure to rinse your print after the peroxide and water
dunking. It is a real wow~! to use peroxide to speed the darkening of
the cyanotype. I teach middle schoolers and to see their mouths drop
open with awe is really a treat!

Keep your fingers Blue!
