Old kettles typically work by using a simple heating element or a flame to heat water. When the kettle is placed on a stove, the heat causes the water inside to warm up and eventually reach a boil. Many traditional kettles feature a whistle that sounds when the water reaches boiling point, indicating that it’s ready for use. These kettles are generally made from materials like stainless steel, aluminum, or enamel-coated metal, which conduct heat effectively.
