Copper is the best heat conductor among all materials used in cookware production. Copper allows the cookware to reach high temperatures quickly, and cool down as soon as it is removed from the heat source - giving you maximum control when cooking. The heat spreads out evenly throughout the cookware, without hot spots, preventing food from sticking during cooking. The cookware's interior is lined in stainless steel, meaning it is non-reactive to acids and alkalines, and is safe to use and easy to clean.
