Thanks for this information, which is most interesting! But this does not
really explain why it would DEEPEN the blues in a cyanotype, which is my
impression. Any suggestions from ferric experts???

I have not had time to do the formal tests yet, but I will keep you posted
when I do. I will include Judy's suggestion, and I will also compare it
with the ammonium dichromate blues... This is going to end up as three
month's work!
