Common Sense for Using Copper Kettles

• thermal conductivityThe thermal conductivity of copper is twice that of aluminum and five times that of iron. Using a copper kettle to boil water for tea can save time and energy. Due to its high thermal conductivity, the copper container heats evenly, and copper kitchenware often makes dishes taste even more delicious.

• Corrosion resistanceCopper is a relatively inert and corrosion-resistant metal that can resist the erosion of the environment on its own copper objects, such as copper kettles. It is also because of this that a large number of bronze artifacts from the Shang and Zhou dynasties and coins used by various feudal dynasties have been preserved in Chinese civilization.

• Disinfection and SterilizationCopper has good antibacterial effects and is a relatively hygienic metal. Therefore, the Chinese have had the habit of using copper washbasins since ancient times. The so-called "golden basin hand-washing" is mostly done with copper basins, rather than true "golden basins". In addition, the Chinese have been using copper vases to cultivate flowers for a long time, making the flowers last longer and look more beautiful.

• Copper green harmlessMany people often mistakenly believe that the copper green on the copper kettle is harmful, and this mistake is similar to that of the Japanese, who also had a similar misunderstanding within the East Asian cultural circle. In recent years, with the development of science and technology, copper green has been proven to be a insoluble compound, which is difficult to be absorbed and will be directly excreted from the body even if it is absorbed into the human body.

• Copper is an essential trace element for the human body.Just like iron deficiency, a lack of copper can also lead to anemia, and it can even affect the development of the nervous system and bones. If you pay attention to the ingredients of infant formula milk, you will find that copper is one of the essential elements in the milk.

• Maintenance of Copper KettlesIf water, salt, acid, or other substances remain on the surface of a copper kettle, it will rust and form "copper green," so if there are such residues, they should be immediately wiped clean with a dry towel. It is recommended to often use a soft towel to wipe the copper kettle, which will make the color of the surface more bright and dazzling. If there is dirt on the inner wall of the copper kettle, it can be cleaned by boiling clean with white vinegar or lemon slices. It is forbidden to use hard objects to polish the surface of the copper kettle. If the copper kettle is not used for a long time or is not wiped, it will gradually lose its luster and color will become dark. In this case, you can use a towel dipped in a little toothpaste to gently wipe the surface, which can make the surface of the copper kettle shine again.
