hi Dutchelm05,
i dont think it was oversatuaration cause i didnt change anything in the process
and last time it worked
still 5% potassium dichromate solution, sensitizing for 30 sec
but temperature might have been an issue.
i did the sensetizing on my balkony in the dark at about 5°C "roomtemperature!"
and i wanted to incorporate Dave's advice to put the plates on a sponge for 20 minutes and leftg them in the cold. before moving them inside the drying box. It might have been another mistake to put the dryingbox next to a heater for another hour. Maybe the temperature switch was too fast.
And again the soap might have had a bad formulation.
But anyway, next time i mix the dichromate in the gelatin from the beginning on.
I'll give you an update as soon as i get it done. Don't worry ill hang in there...
