[Alt-photo] Re: Sulfamic Acid for Paper Acidification

[Serdar Bilici]

Hi Earl,

Yes apparently sulfamic acid is easy to find and affordable. The first time
I heard the name of this acid was in Mike Ware's argyrotype formula. 
IMO, It worked better than most acids often recommended to acidfy papers in
various online forums.

Regards
Serdar

Sulfamic acid is available at the big box home repair stores as grout
cleaner. It is also one of the key ingredients in Mike Ware's argyrotype
formula.
