Had a little time to experiment. Unfortunately I missed the part in the patent that said the paper becomes red sensitive. I had 10 sheets hanging to dry with the safe light on. all but one where exposed. the one that wasn't exposed was hiding in the shadows.

Although it printed well I found out that toning will wipe the print out. I used a .2% sol. of gold toner and the print went black. Fixing the print just washed away the silver and left me with a white sheet.

Will have to try again.
