hi all,

i've just tried the bfk rives 250g (acidified 5% 5mn)

i can't clear the paper, (one time only with success and it was bleached)
i've tried edta, oxalic acid, sodium sulfite, sodium metabisulfite (perhaps slighty better but really not enough) with warm distilled water
potassium oxalate or sodium citrate as developer
mix platinum/palladium or pur palladium

i follow all the advices (not the lime away) of this trade a and i can't find a solution for this beautiful paper.
