No other metal brings sugar or chocolate to their correct working temperatures. Egg whites beaten in copper have more volume, become stiffer and stay firm for longer than egg whites beaten in stainless steel bowls. This is the main reason why copper bowls are being used by pastry chefs. Copper reacts with egg white enabling them to whip to higher peaks and hold texture for longer than other metal, melamine, stoneware or any other material.
