These "A", "B" solutions were put in seperate, clean, old hydrogen peroxide
bottles, after which I placed each into a plain white plastic bag.
Into a wooden cabinate in my cellar they went.
This week (Oct 1996) I was going to clean out my cabinate and make up
some new cyanotype solutions.....checked out the old solutions before
throwing them out...they seemed OK ...tried a few test prints...they
seemed to work OK too. Coatings were as normal yellow-yellow green...
..prints were deep blue and paper white respectively.
2 1/2 years seems like a long time. Sooooo...should I:
a). Throw these solutions out anyway.
b). If it ain't broke...don't fix it.
Thanks
