Kettle

The word kettle originates from Old Norse ketill, "cauldron". The Old English spelling was cetel with initial che- [tʃ] like 'cherry', Middle English (and dialectal) was chetel, both come (together with German Kessel "cauldron") ultimately from Germanic *katilaz, that was borrowed from Latin catillus, diminutive form of catinus "deep vessel for serving or cooking food", which in various contexts is translated as "bowl", "deep dish", or "funnel". == Stovetop kettles ==

kettle on a gas burner; this type, without a lid, is filled through the spout. A modern stovetop kettle is a metal vessel with a flat bottom used to heat water on a stovetop. They usually have a handle on top, a spout, and a lid. Some also have a steam whistle that indicates when the water has reached its boiling point. Kettles are typically made with stainless steel but can also be made from copper or other metals. == Electric kettles ==

Electric kettles may also be used to boil water without the necessity of a stovetop. The heating element is typically fully enclosed, with a power rating of 2–3 kW. This means that the current draw for an electric kettle is up to 13A, which is a significant proportion of the current available for many homes: the main fuse of most homes varies between 20 and 100 amps. In modern designs, once the water has reached its boiling point, the kettle automatically deactivates, preventing the water from boiling away and damaging the heating element. the first confirmed electric kettles were designed in 1891 by an American company, Carpenter Electric Co., In 1922, Leslie Large, an engineer working at Bulpitt & Sons of Birmingham, designed an element of wire wound around a core and sheathed in a metal tube. The element could be immersed directly into water which made the kettle much more efficient than stovetop kettles. In 1955, the newly founded British company Russell Hobbs brought out its stainless steel K1 model as the first fully automatic kettle. A bimetallic strip, heated through a pipe by the steam produced as the water comes to the boil, flexes, and cuts off the current. As little steam is produced before boiling occurs, the bimetallic thermostat is set to activate well below , thus this design works even at higher altitudes where the boiling point is significantly lower. The design has since been widely adopted by other manufacturers. == Whistling kettles ==

A whistling kettle is a kettle fitted with a device that emits an audible whistle when the water in the kettle starts to boil. The action of steam passing through the device causes vibration, in turn creating the sound, known in physics as a tone hole. The exact mechanism by which this occurs was not fully understood until a paper, The Aeroacoustics of a Steam Kettle, was published by R. H. Henrywood, a fourth-year engineering undergraduate at the University of Cambridge, and A. Agarwal, his supervisor, in the journal Physics of Fluids in 2013. Harry Bramson is the inventor of the whistling tea kettle. == Automatic tea kettles ==

Automatic tea kettles are meant to make tea brewing easier, built with the capability to make different kinds of tea without much input from the user. Once set, the automatic tea kettle brings the water to the specific temperature for preparing a given kind of tea, adds the tea to the water, and steeps the tea for the appropriate amount of time. This is because different types of teas must be brewed at different temperatures in order to create a full, balanced flavor. Often they will make a beeping sound to alert the user when the tea is ready, and maintain the temperature of the beverage after preparation. == Kettle gallery ==
