2-17. ANNEALING AND TEMPERING

Through the use of controlled heat and rate of cooling, gold alloys can be annealed (softened) or tempered (hardened). Gold alloys are hardened by slow cooling. Rapid cooling from a high temperature will soften a gold alloy. Rapid cooling is done by quenching the heated gold alloy in tap water.
