* * Can't * * burn ingots at home. Ingots need to undergo chemical reaction at high temperature and high pressure to be fired, which may cause explosion and fire and pose a threat to personal safety. In addition, the production and sales of ingots need to go through strict government supervision and certification, and abide by specific standards and norms. Therefore, for the sake of safety, it is recommended to choose a regular gold and silver jewelry store or certification body to buy or invest in gold ingots, and not to engage in illegal activities such as burning fire at home.
