It was ferric oxalate that had been recently mixed from Bostick and
Sullivan powder.

I would not use kallitype again until I found out what happened to one I
made for John Dugdale 3 or 4 years ago... I was doing kallitype & printed
one of his negatives as a neighborly demo-- procedure as usual. He took it
home & rolled it up or whatever, and it dropped down behind something,
where it rested until it turned up again, recently. It had distinct
stripes of fading across it, regular bands and lines across the center. I
don't have a clue what caused it or how, haven't seen it in my own,
perhaps something in the resting place, but..... it did take away my
appetite for kallitype.
I told John to throw it away....
