Re: Cyanotype Sensitiser Dregs On The Bottom

I think you may be right it's probably some late forming crystal. For the
most part the bottle looks clear. I only waited about an hour before I
filtered it. It's not that much material to be honest. I could always do
another filtering. What affect would including some of the sludge have on
the look of the print?
