1 thought on “Why did Gold Soft now gold and hard”

  1. Why did Gold Soft now get gold and hard, yes, because the previous purification technology was relatively low! Gold 999 or 9999 (more ornaments), the more pure, the soft and easy to deform, but now it is different. There is a kind of gold called three D hard gold, and the purity of gold is also 999!
