Hi David,
I'd consider a hit of 5% dichromate in a 6/6 zia drop mix to be strong.
Also, it's an awful lot for just about any negative developed in pyro,
even if it needed grade 3 paper for silver. I'd go back to 1% or 2%.
However, the very long exposure and mottled look don't sound right
either. I've used a drop of 20% dichromate in a 12/12 8x10 originally
developed for silver and got fine results in a reasonable (maybe 20
minute) exposure, but those weren't pyro negs. It's possible that your
print was drying out during that super-long exposure.
Happy holidays everyone. Don't spend it all in the darkroom.
