Left to right: Argentium Pro 935 (from Rio Grande), Sterlium (from Stuller), Continuum (from Stuller)
These castings are not pickled. They each cast beautifully and any I think one of them is superior to traditional sterling silver. The Argentium and the Sterlium seem to be more firescale resistant than the Continuum. The Argentium and the Sterlium are very white. The downside of Sterlium for me is the lack of fusing ability. The Sterlium will NOT fuse while the Argentium fuses like a dream. I am able to cast something in sections, fuse them together then granulate.

One of the advantages of Argentium is the ability to fuse. Because the pieces were fused together rather than soldering, there will never be a seam visible! And the piece can then be granulated since there is no solder used.
