- Copper cookware is made with copper as the primary component. Copper is a metal that is an excellent conductor of heat. Cookware made from copper is usually lined with either tin or stainless steel. Brass cookware contains a combination of copper and zinc. When copper is consumed by humans, small trace amounts are good for one's health. However, large amounts consumed at once or over a period of time can be poisonous. When sufficient amounts of dissolved copper are consumed, it can cause diarrhea, nausea and vomiting. A safe amount of copper for daily intake has not been determined.
- Because of copper's ability to conduct heat well, pots and pans made from copper are often a preferred choice for range-top cooking. Some cooks choose copper cookware when preparing foods and delicate sauces that need to be cooked at precise temperatures. Copper cookware is also used for decorative purposes because of its distinctive color and shine.
- The Food and Drug Administration (FDA) warns consumers against using cookware made from unlined copper for general cooking purposes. Without the protective lining of tin or stainless steel, it is possible for certain foods to cause the copper to dissolve during the heating process. Acidic foods can cause the protective lining to dissolve if they are cooked or stored for long periods of time. It is also possible to damage the lining with harsh scrubbing and scouring. Some copper cookware may contain nickel in the lining. People with a nickel allergy should not use copper cookware that contains nickel.
- To avoid the risk of copper poisoning, always use copper cookware that is lined. Do not use copper cookware that has become badly scratched and has lost some of its protective lining. Avoid long cooking or storage times when preparing acidic foods.
- With proper care, copper cookware can be used safely for a long time. Follow the manufacturer's recommendations for the care and cleaning of copper cookware. In general, exposed outer copper surfaces should be cleaned with an anti-tarnish creme. Do not use abrasive cleaners to clean copper surfaces. To avoid warping, always allow copper cookware to cool before washing.
