An induction cooktop involves the electrical heating of a cooking vessel by magnetic induction instead of by radiation or thermal conduction from an electrical heating element or from a flame. Because inductive heating directly heats the vessel, very rapid increases in temperature can be achieved and changes in heat settings are fast, similar ...
An induction cooker wirelessly transfers electrical energy by induction from a coil of wire into a metal vessel. The coil is mounted under the cooking surface, and a low radio frequency (typically ~25-50 kHz [1]) alternating current is passed through it. The current in the coil creates a dynamic electromagnetic field which is strongly magnetic.
In a kitchen the hob is a projection, shelf, grate or bench for holding food or utensils at the back or side of a hearth to keep them warm, or an internal chimney-corner. In modern British English usage, the word refers to a cooktop or hotplate , as distinguished from an oven .
Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...
Pontil scar on the base of a free-blown glass bowl. A pontil mark or punt mark is the scar where the pontil, punty or punt was broken from a work of blown glass.The presence of such a scar indicates that a glass bottle or bowl was blown freehand, while the absence of a punt mark suggests either that the mark has been obliterated or that the work was mold-blown.
Induction heating is a non contact heating process which uses the principle of electromagnetic induction to produce heat inside the surface layer of a work-piece. By placing a conductive material into a strong alternating magnetic field, electric current can be made to flow in the material thereby creating heat due to the I 2 R losses in the material.
Gas mark 1 is 275 degrees Fahrenheit (135 degrees Celsius). [citation needed] Oven temperatures increase by 25 °F (14 °C) for each gas mark step. Above Gas Mark 1, the scale markings increase by one for each step. Below Gas Mark 1, the scale markings halve at each step, each representing a decrease of 25 °F (14 °C).
Extractor hoods may be made from a variety of materials, including stainless steel, copper, bronze, nickel silver, zinc, tempered glass, wood, aluminum, brass, heat-resistant plastics, and more. NFPA 96 Standard for Ventilation Control and Fire Protection of Commercial Cooking says that mesh filters shall not be used.
