A tea kettle is a small pot designed for boiling water to make tea. It usually has a spout for pouring, a handle for easy lifting, and a hinged lid to keep the water inside from evaporating. Some have whistles attached to the spout that will let out a loud sound when the water reaches a boil, alerting the tea drinker that their beverage is ready. Tea kettles can be made from various materials like metals, glass, or ceramic, and come in many different sizes and designs. While they are most commonly used to make tea, they can also be used to heat up water for other purposes like French press coffee or oatmeal.
