The emission of visible light from a substance or object as a result of heating it to a high temperature. The color of the light emitted from solids and liquids is a function of their chemical structure and their temperature; the higher the temperature, the more intense and even the distribution of frequencies is (that is, higher temperatures create brighter and whiter light than lower temperatures).
On passing a current through the carbon the small rod is heated to incandescence, and imparts heat to the surrounding mass.
Edison in 1878 again attacked the problem of producing light by the incandescence of platinum.
It combines with fluorine with incandescence at ordinary temperatures, and with chlorine at 250-300°; carbon, silicon, and boron, when heated with it in the electric furnace, give crystals harder than the ruby.
- Independently of the question of the application of external heating, the furnaces used in electrometallurgy may be broadly classified into (i.) arc furnaces, in which the intense heat of the electric arc is utilized, and (ii.) resistance and incandescence furnaces, in which the heat is generated by an electric current overcoming the resistance of an inferior conductor.
It is not necessary that all electric furnaces shall be run at these high temperatures; obviously, those of the incandescence or resistance type may be worked at any convenient temperature below the maximum.
