The photographic process which causes argyria is normally associated
with silver halides, such as silver chloride and bromide. So one might
assume that silver citrate, which is more stable than silver chloride
might not be a problem. Unfortunately experience with Silver Oz which is
silver citrate has shown that it too can cause argyria.

What about silver citrate? There have been discussions on this list on
how to make it. But I have read that silver citrate is also highly
likely to cause argryia? Is that not true?

That sounds fine. That's what I do as well. I don't think there is
any difference between CS and EIS for purposes of this forum.
EIS is Electrically Isolated Silver, which is a form of CS, with
around 10-20% colloidal silver particles, and 80-90% ionic silver
particles, which I understand are AgOH.
CS is what most people call EIS. In fact the only place I have heard
EIS is on this forum. The rest of the world calls it CS. EIS is
more accurate, I believe, only because there are other ways to make
CS, such as from nano-silver-powder, which apparently involves no
electricity. So I suppose it's good to distinguish them by using the
abbrev EIS.
