Casting Argentium Sterlingr for the first time

Hi all,

I’ve been casting some items for earrings and bracelets ( little
fish, a popular theme around here) using Argentium for the first
time. Although I followed Rio’s sheet as best I could, I
never achieved bright, clean castings as I was expecting because of
what I had read. My castings were covered with a white coating which
came right off very easily, but put another step in the process. Any
advice on this?
