The flame then melts the top of the mass of good gasoline, which moves upward throughout the wick by way of capillary action to generally be continuously burnt, therefore sustaining a constant flame.

Nonetheless, this Component of the flame is quite smaller and releases little heat Electrical power. The blue color is because of chemiluminescence, though the visible yellow shade is because of radiative emission from scorching soot particles.
