Izzóing

Izzóing is a term used to describe the phenomenon of an object becoming incandescent due to high temperature. This typically occurs when an object is heated to a point where it begins to emit visible light. The color of the emitted light is dependent on the temperature of the object, following the principles of black-body radiation. At lower temperatures, the light emitted is often in the red spectrum, gradually shifting through orange, yellow, and white as the temperature increases. At very high temperatures, objects can even appear bluish-white.

The term itself is derived from the Hungarian word "izzó," meaning incandescent or glowing. This phenomenon is commonly observed in everyday objects such as heated metal filaments in incandescent light bulbs, the coals in a fire, or lava from volcanic activity. Understanding izzóing is important in various scientific and industrial applications, including metallurgy, furnace design, and astrodynamics, where precise control and prediction of light emission from heated bodies are crucial. Factors influencing the rate and intensity of izzóing include the material's properties, such as its emissivity, and the ambient environment.
