[Alt-photo] Re: Was Sulfamic now VDB and pt/pd gold leaf

I certainly wish u would...
It was an old & cheap way to detox used fixer, stirring steel wool into it.
The Silver is replaced with iron & you get AgO as a precipitate...
A really nice stable, hard to break up compound...
Have a great weekend...

Hi Andy, I'm not familiar with the procedure you describe, but my gut
feeling is that you'll get elementary silver that way.

Loris.
