kettle

A kettle is a vessel for heating water, typically heated on a stove or by an electric base. It has a body, a handle, a spout, and a lid, and many models include a whistle that sounds when the water boils.

There are two main categories: stovetop kettles and electric kettles. Stovetop kettles heat directly on a flame or hob and usually whistle when boiling. Electric kettles contain an internal heating element and an automatic switch-off when the water reaches boiling temperature.

Some kettles are designed for precise pouring, notably gooseneck kettles used in pour-over coffee and tea. They feature a long, narrow spout for controlled flow, while others emphasize rapid heating, durability, or aesthetics.

Materials vary. Stainless steel is common for durability and heat conduction; copper and aluminum heat quickly but may require maintenance. Glass and ceramic kettles are popular for visibility and style. Interiors may be lined to prevent reaction with water.

Maintenance and safety include descaling to remove mineral buildup, especially in hard water. Use appropriate power supplies for electric kettles and inspect cords for damage. Do not heat an empty kettle.

The modern electric kettle became widespread in the mid-20th century, while stovetop kettles have a longer history dating to the 19th century. Today kettles are produced in many sizes and finishes for homes, offices, and professional kitchens.
