More fun experimentation with metal clay. This time it’s with silver ArtClay. Unlike BronzClay that has to be fired in an oxygen-free environment (activated carbon) to prevent the copper from inhaling it and becoming cuprous oxide (a.k.a. firescale), this metal clay is .999 (or 99.9% pure silver) so it can be fired in the open kiln on a shelf, or even with a torch. The binder burns away and leaves fine silver to sinter.
As with other metal clays, the fired piece distorts and shrinks a bit. What started as a square ring with round corners is now a trapezoid. I love this randomness, but would definitely use lost wax if I needed accurate geometry.
