A kettle, sometimes called teakettle, tea kettle or the pot, is a small kitchen appliance Home appliances are electrical/mechanical appliances which accomplish some household functions, such as cooking or cleaning used for boiling Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure. Thus, a liquid may also boil when the pressure of the water in preparation for making tea Tea is the agricultural product of the leaves, leaf buds, and internodes of the Camellia sinensis plant, prepared and cured by various methods. "Tea" also refers to the aromatic beverage prepared from the cured leaves by combination with hot or boiling water, and is the common name for the Camellia sinensis plant itself or other beverages requiring hot water. Kettles often resemble teapots A teapot is a vessel used for steeping tea leaves or an herbal mix in near-boiling water. Tea may be either in a tea bag or loose, in which case a tea strainer will be needed, either to hold the leaves as they steep or to catch the leaves inside the teapot when the tea is poured. Teapots usually have an opening with a lid at their top, where the, but are used to boil water, not to brew tea.
Kettles can either be heated by placing on a stove A stove is an enclosed heated space. The term is commonly taken to mean an enclosed space in which fuel is burned to provide heating, either to heat the space in which the stove is situated or to heat the stove itself, and items placed on it. This article is principally concerned with enclosed stoves burning solid fuels for room heating, or by their own heating element A heating element converts electricity into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element.

This article is principally concerned with enclosed stoves burning solid fuels for room heating-mounted kettles also have a steam whistle that indicates when the water has reached boiling point.
Electric kettles
Electric water kettle designed by Peter Behrens for AEG in 1909Electric kettles are normally constructed out of durable plastic or steel (with a plastic handle) and powered by mains electricity Mains is the general-purpose alternating current electric power supply. In the US, electric power is referred to by several names including household power, household electricity, powerline, domestic power, wall power, line power, AC power, city power, street power, and grid power. In Canada, it is often called hydro, because much of the Canadian. In modern designs, once the water has reached boiling, the kettle automatically deactivates to prevent the water boiling away and damaging the heating element A heating element converts electricity into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element.
Corded kettles generally use detachable IEC C15 and C16 IEC connector is the common name for the set of thirteen mains electricity cable mount female connectors and thirteen panel mount male connector (called the inlet) defined by International Electrotechnical Commission (IEC) specification IEC 60320 (formerly IEC 320). When used with no other qualifiers, IEC connector usually refers specifically to connections.
"Cordless" kettles, sometimes called "jettles", became popular in the late 1980s and 1990s. These kettles consist of a plastic base that connects to the mains outlet and a separate kettle. They both have electrical contacts that connect to supply power to the kettle when it is placed on top of the base, and the kettle can be easily detached to allow movement to the sink and elsewhere.
Similar to the electric kettle is the electric water boiler An electric water boiler, also called an electric dispensing pot, electric water heater, electric water urn, or electric kettle, is a consumer electronics small appliance used for boiling water and possibly maintaining it at a constant temperature. It is typically used to provide an immediate source of hot water for making tea, hot chocolate,, a vacuum flask A vacuum flask, colloquially called a thermos after a genericized ubiquitous brand, is a storage vessel which provides thermal insulation by interposing a partial vacuum between the contents and the ambient environment. The evacuated region of the partial vacuum removes material that could serve as a heat conductor or carrier, enabling the flask with a heating element that boils water and maintains it at a constant temperature. These are particularly popular in East Asia East Asia or Eastern Asia is a subregion of Asia that can be defined in either geographical or cultural terms. Geographically and geo-politically, it covers about 12,000,000 km2 (4,600,000 sq mi), or about 28 percent of the Asian continent, about 15 percent bigger than the area of Europe and also in Israel, where they are used during the Jewish Sabbath, the day of rest.

The word kettle originates from Latin catillus, which in various contexts is translated as bowl, deep dish, or funnel. A kettle is probably the most ancient kind of metal cooking utensil.[citation needed] Common materials were wrought iron Wrought iron is an iron alloy with a very low carbon content, in comparison to steel, and has fibrous inclusions, known as slag. This is what gives it a "grain" resembling wood, which is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile and easily welded. Historically, it was known as & and pressed steel plate.
From the 1880s to the 1920s, people used cast iron Cast iron usually refers to grey iron, but also identifies a large group of ferrous alloys, which solidify with a eutectic. The colour of a fractured surface can be used to identify an alloy. White cast iron is named after its white surface when fractured, due to its carbide impurities which allow cracks to pass straight through. Grey cast iron is kettles to heat water for hot beverages like tea and coffee. Cast iron kettles were cast from a mould and showed good thermal qualities. These kettles were heated on top of a stove.
During the 1920s and 1930s, people used kerosene Kerosene, sometimes spelled kerosine in scientific and industrial usage, also known as paraffin in UK and South Africa, is a combustible hydrocarbon liquid. The name is derived from Greek keros . The word Kerosene was registered as a trademark by Abraham Gesner in 1854 and for several years only the North American Gas Light Company and the Downer kettles. These kettles were popular because a stove was no longer needed to heat water, thus there was no need to heat up the entire stove just for a cup of tea, and less thermal energy was required to heat up the water. However, this appliance did create kerosene fumes.
In Australia, chrome-plated steel Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten. Carbon and other elements act as a hardening agent, preventing kettles were popular in city areas in 1938, as they ran on electricity. Electricity in the country at the time was rare. These kettles had no exposed coil, but rather one under a flat bottom inside the kettle. This kettle had some safety features like an overload cut out switch. The cord was cotton insulated, which was safe, when new. As it became worn it would expose the coil and the possibility of electrocution could occur. The plug was a Bakelite Bakelite , or polyoxybenzylmethylenglycolanhydride, is an early plastic. It is a thermosetting phenol formaldehyde resin, formed from an elimination reaction of phenol with formaldehyde, usually with a wood flour filler. It was developed in 1907–1909 by Belgian chemist Dr. Leo Baekeland plug.
In 1949 ceramic A ceramic is an inorganic, non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure, or may be amorphous . Because most common ceramics are crystalline, the definition of ceramic is often restricted to inorganic crystalline materials, as opposed to the non- kettles, which ran on electricity, were first released. They made it more efficient to boil water. These kettles were also called jugs as they resembled a jug shape. These kettles also have a cotton-insulated cord, like thier 1938 counterparts.
From the 1950s through the 1970s, the development of the ceramic jug continued. The kettles started to show more safety features like whistles and cut out features. They typically had Bakelite handles and their operations and aesthetics were improved. During this time it was still possible to buy stovetop ovens.
During the 1980s, polymer A polymer is a large molecule composed of repeating structural units typically connected by covalent chemical bonds. While polymer in popular usage suggests plastic, the term actually refers to a large class of natural and synthetic materials with a wide variety of properties body kettles were first released. Some features of this new kettle's materials were, they were more durable and were poor conductors of heat. These jugs new materials made them cheaper to produce on a mass production scale. These kettles also had safety features like whistles, cutout switches and had windows in the side to see how much water was in the kettle meaning never having to lift the lid off. Also the cord insulation was made of plastic, meaning wear on the cords no longer exposed wire.
In the 1990s, kettles were improved by having a base, which allowed the jug to swivel and be detached. This meant water could be poured farther away from the plug meaning less chance of electrocution.
In the 2000s, more efficient stainless steel In metallurgy stainless steel, also known as inox steel or inox from French "inoxydable", is defined as a steel alloy with a minimum of 10.5 or 11% chromium content by mass. Stainless steel does not stain, corrode, or rust as easily as ordinary steel, but it is not stain-proof. It is also called corrosion-resistant steel or CRES when the kettles with polymer handles featured a cut-out switch, which stopped heating the kettle after the water boiled. They also had a cut-out switch on the base so when the kettle was put on the back on the base, it would not start boiling again. Also, it cut out power supply if lifted off the base, making it safer.
