Loris and Christina,
Thanks for the info on argyrotype. I have concluded that my problems
must stem from my sulfamic acid which I bought at the hardware store. It is
labled sulfamic acid and nothing else, but, being an industrial tile
cleaner, it may have other stuff in it. If any of you find an inexpensive,
paper which works well for you I'll try again with aa lab grade sulfamic
acid.
