Stainless steel cutlery can turn black due to a process called oxidation. When stainless steel comes into contact with certain substances like sulfur compounds found in food, it can cause a chemical reaction that leads to the formation of a black layer on the surface of the cutlery. This black layer is typically a thin layer of iron oxide, also known as tarnish, which can be removed with proper cleaning and maintenance. Additionally, exposure to high heat or prolonged contact with acidic foods can also contribute to the discoloration of stainless steel cutlery. **
