Sterling silver wire is .925 silver. Sterling silver is 925 parts fine silver and 75 parts copper. This makes a strong wire that is durable for jewelry findings, earwires, and components. Sterling silver can be co-fired in silver clay by first depletion gilding the metal using Silver Prep. Sterling silver wire can be work hardened by stretching, twisting, rolling, hammering, tumbling, etc. It can also be heat hardened.
Heat Hardening Sterling Silver: Place items in kiln to be hardened. Fast ramp to 750F and hold for 30 minutes. Remove and quench if possible. Quenching quickly realigns the crystal structure to result in additional hardness.
