A controlled burn off during the Northwest Territories, showing versions in the flame colour as a consequence of temperature. The hottest elements in close proximity to the bottom appear 솔루션분양 yellowish-white, although the cooler upper pieces seem purple. The glow of the flame is elaborate. Black-body radiation is emitted from soot, gas, and gas particles, however the soot particles are far too compact to behave like perfect blackbodies.
