What causes the discoloration of Silver Porcelain by Tiancheng utensils during use? How is it resolved?

The surface of Silver Porcelain by Tiancheng products is fine silver. When it comes into contact with harmful elements, a sulfidation reaction occurs, causing it to quickly turn black or yellow, which is a normal phenomenon. The best solution is to wipe it with a “food-grade silver cleaner cotton,” which not only restores the silver’s luster but also causes minimal wear, and is non-toxic and harmless.
