FYI:
Arctic Cotton: Eriophorum (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family. They are found throughout the arctic, subarctic, and temperate portions of the Northern Hemisphere in acid bog habitats, being particularly abundant in Arctic tundra regions. (per Wikipedia)

I like palladium, because I like it warm. The disadvantage of pure palladium coating is its tendecy to solarize. Mixings of palladium and platinum would solve this problem, but the price of platinum seems to grow up from day to day.
So I am experimenting with Mike Ware´s ammonium palladate recipe. The resulting colour of this POP is depending on humidity of the paper - best 50-80%( the more the cooler the hue). Below 50% RH there is only partial printout and considerable development, above 80% RH the tonal range tends to weaken. It is possible to dry the coated paper in a drying cabinet and humidify controlled before the exposure.
During the last days the climate in my darkroom was so moisty as in a jungle - between 95 and 97% RH. This is far too much! However I tried it.
