Stainless steel can turn black under certain conditions. This discoloration, known as "tea staining," is caused by the formation of a thin layer of iron oxide on the surface of the stainless steel. This can occur when the stainless steel is exposed to high levels of chloride, such as in coastal or industrial environments. Regular cleaning and maintenance can help prevent this discoloration and keep stainless steel looking its best. **

Additionally, exposure to high heat or prolonged contact with acidic foods can also contribute to the discoloration of stainless steel cutlery. **

The thickness and color of the oxide layer can vary depending on the temperature and duration of the heating process. **
