Common knowledge about the use of copper pots

• Thermal conductivityThe thermal conductivity of copper is twice that of aluminum and five times that of iron. Using a copper kettle to brew tea saves time and energy. Due to its high thermal conductivity, the container heats evenly, and copper kitchenware often enhances the taste of dishes.

• Corrosion resistanceCopper is a metal that is not very reactive and resistant to corrosion, capable of resisting the erosion caused by the environment on copper objects (such as copper pots). For this reason, there are many copper artifacts from the Shang and Zhou dynasties, as well as copper coins used by various feudal dynasties throughout history, preserved in Chinese civilization.

• Disinfection and sterilizationCopper has excellent antibacterial properties and is a relatively hygienic metal. Therefore, people in China have had the habit of using copper washbasins since ancient times. The so-called “washing hands with a golden basin” also typically involves using a copper basin, rather than a real gold one. Additionally, Chinese people used copper flower vases at an early stage to help flowers last longer and look more beautiful.

• Copper green is harmlessMany people often mistakenly believe that copper green on copper pots is harmful. This was also a similar misconception among the Japanese, who belong to the same East Asian cultural sphere. In recent years, with the development of science and technology,Copper green has been proven to be a insoluble compound; it is very difficult to absorb, and even if ingested, it is not absorbed and is directly excreted from the body.

• Copper is an essential trace element for the human bodyJust like iron deficiency, copper deficiency can also cause anemia, and may even affect the development of nerves and bones. If you pay close attention to the formula for infant milk powder, you will notice that copper is one of the essential elements in it.

• Maintenance of the copper kettleIf water, salt, acid, or other substances remain on the surface of the copper pot, it will rust and produce "verdigris." Therefore, any such residues should be immediately wiped clean with a dry towel. Regularly using a soft towel to clean the copper pot will make its surface color more vibrant and shiny.If dirt appears on the inner wall of the copper kettle, you can use white vinegar or lemon slices mixed with water and boiled to clean it thoroughly; avoid using hard objects to scratch the surface of the kettle.If the copper pot is not used for a long time or its surface is not cleaned, it will gradually lose its luster and become darker in color. In such cases, you can dip a towel in a little toothpaste powder and gently wipe it over the surface, which will restore its shine.
