Re: Cuprotype



... It still could be the clearing time and I am just having trouble clearing the Iron out of this paper. I was also wondering if I have Iron in the wash water. I live in a large city and have been using tap water for the final wash.
It could be also some iron left in the paper due to its alkaline buffer.
Try also to acidify the paper -and let it dry- before the coating, for example with the same solution used for the washing bath (0.5% acetic acid).
