What happens to gold fillings during cremation?

During cremation, gold fillings generally do not melt due to the high temperature of the cremation process, which typically reaches around 1400 to 1800 degrees Fahrenheit. Instead, they may become dislodged from the remains or remain intact as they are resistant to heat. Any gold that is not retained may be recovered later during the crematory processing of the ashes. Ultimately, the fate of gold fillings depends on their specific composition and how they are affected by the cremation environment.
