Argentium Sterling® Casting details

I have had a few requests for more details on the methods I use to cast my jewelry. For me, it's got to be cheap! I have been collecting lapidary and silversmith equipment for several years, most of it used. Some of the equipment I started with, has never been replaced simply because I have become so accustom to it and there seems to be no need for replacement.

Please note that when I cast, I usually cast around two troy ounces of AS at a time.

The torch I use is a BernzOmatic® Jet Torch Kit (JTH7). Using this torch with MAPP gas, produces a flame that, at least for me, is perfect for casting with Argentium Sterling® Silver. I turn it up full blast and the AS melts rapidly, and yet doesn’t overheat too quickly. Although I have other torches now, this is my favorite for casting because it helps me be as consistent as possible.
As I am melting the Argentium Sterling® Silver, I add a pinch of Borax. I try to heat the AS only as long as needed. As soon as it is liquid, I start the centrifuge.


The centrifuge I use is a simple to use Neycraft® Centrifugal Caster. I take the flask directly from the kiln to the centrifuge. The time it takes for me to put the flask in the centrifuge, and heat the metal, seems to allow the flask time to cool to the proper temperature for casting. After the piece is cast, I allow the flask to cool to room temperature before removing the piece. This helps make the Argentium Sterling® Silver stronger and more durable.

Although this process is quite simple, it has bought me very consistent results that I am very pleased with. Hope this helps! Good luck and Happy Casting :).
