light from heat the phenomenon of light emission by a body as its temperature is raised
Emission of light due to high temperature of the emitting material Any other emission of light is called luminescence
{i} glowing, shining, production of light by an object that has been heated to a high temperature; light produced by a heated object; state of being filled with an intense emotion, fervour
The emission of luminous flux (glowing) characteristic of bodies at high temperature
The emission of visible electromagnetic radiation due to the thermal excitation of atoms or molecules
In lamping terms, the reaction of certain rare earth metallic element salts to intense heat Visible light (and heat) is generated from the molecular action of these elements raised to high temperatures "Mantles" (greatly simplified!) are structures of fabric treated with metallic salts such as Thorium, Cesium or Yttrium oxides, then sintered and shaped to form either rigid or "rag" mantles Rigid mantles, like the Aladdin or the old gas lamp mantle, are structures of ASH protected in their unburned form by collodion so they may be shipped to the user ANY mantle, once burned, is (again) naught but ash, and is thus VERY fragile
