Reason for using pure copper for “Copper sierra cup REST 320/480/600” without coating
For model “Copper sierra cup REST 320/480/600”, the solid pure copper is being used without coating. In the market, some products use tin or nickel plating. The reason for tin or nickel plating is to prevent discoloration of food due to verdigris.
After cooking, discoloration of food can be prevented by transferring the food to another container or placing it on a plate. The verdigris is harmless to the body, but even if it is plated, it is not recommended to leave food in it for long periods of time. Also, if used with a heat source where temperature control is difficult, such as cooking over an open flame, the heat will cause the tin and nickel to melt and burn, and copper will be exposed.
As it’s used, the pure copper will form a coating on the surface of copper and the process of it turning into an amber color can be enjoyed over time.
Copper is an important nutrient for the human body, and when copper is used for containers and cooking utensils, as it is made from a pure solid copper, it may be naturally absorbed by the human body.
