A teakettle ('''tea kettle''') is a small Kitchen Appliance used for Boil ing water in preparation for making Tea or other beverages requiring hot water. Kettles may be Electric or for Stove top use. A teakettle is usually a Kettle with a spout and (usually) a lid. There are also lidless kettles, filled with water through the spout. Some teakettles have a whistle attached to the spout, to signal the moment when the water starts boiling. ELECTRIC KETTLES electric kettle]] Electric kettles automate the process of boiling water, typically doing so more quickly than regular kettles. They have a heating electrical element, made of a very hard Resistant material. The first electric kettle was shown at the Chicago World's Fair , in 1893 , using the electrical heat radiator concept devised earlier by R. E. B. Crompton. This was welded to the kettle's bottom and led to a large waste of heat. In 1923 , Arthur L. Large, from Birmingham , England, invented the immersed heating Resistor . A Safety Valve was introduced by kettle maker Walter H. Bullpitt, also from Birmingham, in 1931 . Modern electric teakettles vary in design from simple kettles with electric heater elements to more advanced ones, with thermal and water level sensors, cordless ones, etc. A cordless teakettle consists basically of two separable parts: a kettle and a base with electrical connection. When the kettle stands on the base the heating element in the kettle is powered through the base. Tea is not made in the kettle itself; a Teapot serves this purpose. An exception is the Japan ese Tetsubin which can be used for both boiling water and brewing tea. SEE ALSO REFERENCES
