[Alt-photo] Re: Was Sulfamic now Argyrotype

[Marek Matusz]

Thanks Loris,
 
I tried a test strip yesterday and it worked great. Great DMAX, beautiful tonal gradation. Today on the dry test stip I noticed some general fog (stain). I can think of two possibilities. I used hydrochloric acid (muratic acid) to wash  the FA soft press paper. Any residual chloride would be incopatible with the silver chemistry resulting in some silver chloride precipitation. I also did not acidify the water for developing. Any more insight from long time argyrotype practitioners?
I really like the pruplish gray of the gold toner highlights
Good news is I picked up a 1lb of sulfamic acid at Home Deport for about $6 for furter experimentation
