White Heat

"White heat" refers to an extreme level of heat where a substance emits a bright white glow, typically seen in metals like iron or steel when they are heated to very high temperatures. This phenomenon occurs because the material has reached a state where it radiates light across a broad spectrum, including visible light. In a broader context, "white heat" can also describe intense activity or excitement in a particular situation, such as a heated debate or a moment of high creativity. It captures both literal and metaphorical extremes of energy and intensity.
